cmake: replace internal option with a new testbins target
To allow building test binaries without test certs, replacing
`_CURL_SKIP_BUILD_CERTS` internal option with a build target that is
similar to `testdeps`, but without building the test certificates.

To make building test binaries a little bit faster, with less noisy
output, and without having to reconfigure the build.

cmake: add native clang-tidy support for tests, with concatenated sources
Tests are build in "unity"-style, by including sources into an umbrella
C files (similar to how CMake unity works). This does not play well with
clang-tidy, which seems to unconditionally ignore C sources included
like this. To fix it, curl's CMake implements a manual clang-tidy
support for tests, which  compiles sources one-by-one, while also making
sure sources compile cleanly standalone (e.g. all sources need to
include `first.h`). The manual clang-tidy implementation is fragile, and
performance, in particular when targeting Windows, is abysmal.

This patch introduces an alternate solution, enabled by the
`_CURL_TESTS_CONCAT=ON` option. In this mode, umbrella sources include
the actual sources instead of `#including` them. Allowing to use CMake's
built-in clang-tidy support to compile them, with clang-tidy actually
checking the sources. Making the manual clang-tidy support unnecessary.
In the Windows CI job it results in a 4x performance improvement (4m ->
1m), making it practical to run clang-tidy on tests on Windows, in CI.

The main downside is that clang-tidy doesn't understand the `#line`
directive. Meaning issues found show the wrong filename and line number
next to them. It's not impossible to locate errors this way, but also
not convenient.

Minor/potential downside is that the concatenated source needs to be
reassembled each time an original source is updated. This may result in
more copying on the disk when used in local development. The largest
source is 1.4MB, so probably not a show-stopper on most machines.

Another is the complexity of maintaining two methods in parallel, which
may be necessary till clang-tidy understands `#line`:
https://github.com/llvm/llvm-project/issues/62405

This solution may in theory also enable adding clang-tidy support for
tests in autotools, though I haven't tried.

Targeted for curl CI for now, and used in a GHA/windows job. 100%
experimental, not recommended outside these.

build: tidy up compiler definition for tests
- tests: merge cmake commands.
- tests: use `target_compile_definitions()`.
- tests/server: use generator expression for platform-specific macro.
- tests/unit: sync `Makefile.am` comment with cmake.
- tests/unit: merge two `AM_CPPFLAGS` lines to keep synced with cmake.
- tests: move macro definitions to `first.h` headers from build level.
  `CURL_NO_OLDIES`, `CURL_DISABLE_DEPRECATION`, `WITHOUT_LIBCURL`,
  `CURL_STATICLIB` (for servers).
  To share more logic.
  Pass `CURL_STATICLIB` in server on all platforms for simplicity.
  (On non-Windows, it's a no-op. It's already done like this with curlu
  and libcurltool.)

Also for lib:
- lib: merge commands.
- lib: sync macro order with tests (also in `Makefile.am`).

tests: move curlcheck.h to libtest as unitcheck.h
To simplify dependencies, and sync tunits and units builds further.

`curlcheck.h` already depended on logic implemented within libtests:
it referenced a global variable (`unitfail`) defined in `first.c` and
declared in `test.h`.

Also:
- rename to `unitcheck.h` to indicate it's meant for unit tests.
- make `unitcheck.h` include `first.h` instead of `test.h`.
  This brings header use closer to libtests. It also includes
  `curlx/curlx.h` for all unit tests by default now.
- move `unitfail` declaration from `test.h` to `first.h`.
  To match its definition in `first.c`.
- drop now redundant per-test curlx header includes.

build: split .c and .h file lists in tests
It allows to pass `.h` files only where they are really needed, which is
`EXTRA_DIST` (or `*SOURCES`) for autotools.

Also:
- rename variables to be shorter and consistent.
- drop references to non-local headers. We don't need to pass them as
  dist sources.
- drop empty variables and references, after the above.
- server: add placeholder `UTIL_H`.

build: fix libcurltool with cmake and tunits, related tidy-ups
Sync how libcurltool is built in different modes and build systems.

cmake:
- build libcurltool with curlx when building shared libcurl.
  To make it possible to use standard libcurl when linking tunits.
  Also syncing this with autotools.
  The remaining difference is that cmake allows to select shared or
  static for curl tool and tests/examples independently.
- fix to link with libcurl instead of libcurlu.
  To sync with autotools and to link with the standard libcurl for
  tool unit tests.
- fix `source_group()` to always include curlx sources.
- add missing 'curlx header files' source group.

autotools:
- build libcurltool without curlx when building static libcurl in
  non-unity builds.
  To avoid double compilation, just to be thrown away at link time.
  Also to sync with unity builds.

both:
- sync source order between autotools and cmake.
- make sure to pass all headers with both autotools and cmake.
  This is a no-op with cmake. Maybe a future patch should make sure
  to not pass those to remove that noise.

build: drop explicit curlx from hdr paths, refer headers with curlx/ prefix
To make all src and test code refer to curlx headers the same way.

Also:
- src: move `curlx.h` include to `tool_setup.h`.
- src/tool_setup.h: drop stray `curlx/timeval.h`.
- servers: de-duplicate `curlx.h` and `curl_setup.h` includes.
- libtests, units: drop stray curlx sub-headers in favor of
  `<curlx/curlx.h>`.
- tests: include `curlx.h` with `<>` instead of `""`. To match
  other parts of the codebase.

build: sync tests unity builds between cmake and autotools
Instead of relying on CMake's built-in unity feature, use `mk-unity.pl`,
as already done with autotools. It simplified the build, shortens logs
and makes debugging easier because of the fewer build variations.
It also allows testing / fixing with cmake and those automatically apply
to autotools builds too. cmake builds can be much-much faster, esp.
when working the builds themselves.

It also enables "unity" in old cmake versions. Basically every test
target is a single generated .c source.

Also:
- drop a `lib` unity workaround for libtests with autotools after fixing
  the issue in libtests itself. It drops a few exceptions and makes
  libcurl build faster (in autotools unity).
- fix another `lib` autotools unity issue and drop the workaround for it
  from `mk-unity.pl`. `srcdir` was missing from the header path.
- simplify `mk-unity.pl` command-lines, drop exclusions.

tests: always make bundles, adapt build and tests
Make test bundles the default. Drop non-bundle build mode.
Also do all the optimizations and tidy-ups this allows, simpler builds,
less bundle exceptions, streamlined build mechanics.

Also rework the init/deinit macro magic for unit tests. The new method
allows using unique init/deinit function names, and calling them with
arguments. This is in turn makes it possible to reduce the use of global
variables.

Note this drop existing build options `-DCURL_TEST_BUNDLES=` from cmake
and `--enable-test-bundles` / `--disable-test-bundles` from autotools.

Also:
- rename test entry functions to have unique names: `test_<testname>`
  This removes the last exception that was handled in the generator.
- fix `make dist` to not miss test sources with test bundles enabled.
- sync and merge `tests/mk-bundle.pl` into `scripts/mk-unity.pl`.
- mk-unity.pl: add `--embed` option and use it when `CURL_CLANG_TIDY=ON`
  to ensure that `clang-tidy` does not miss external test C sources.
  (because `clang-tidy` ignores code that's #included.)
- tests/unit: drop no-op setup/stop functions.
- tests: reduce symbol scopes, global macros, other fixes and tidy-ups.
- tool1621: fix to run, also fix it to pass.
- sockfilt: fix Windows compiler warning in certain unity include order,
  by explicitly including `warnless.h`.

curlx: move into to curlx/
Move curlx_ functions into its own subdir.

The idea is to use the curlx_ prefix proper on these functions, and use
these same function names both in tool, lib and test suite source code.
Stop the previous special #define setup for curlx_ names.

The printf defines are now done for the library alone. Tests no longer
use the printf defines. The tool code sets its own defines. The printf
functions are not curlx, they are publicly available.

The strcase defines are not curlx_ functions and should not be used by
tool or server code.

dynbuf, warnless, base64, strparse, timeval, timediff are now proper
curlx functions.

When libcurl is built statically, the functions from the library can be
used as-is. The key is then that the functions must work as-is, without
having to be recompiled for use in tool/tests. This avoids symbol
collisions - when libcurl is built statically, we use those functions
directly when building the tool/tests. When libcurl is shared, we
build/link them separately for the tool/tests.
