Make autotools and cmake detect DES support in OpenSSL and mbedTLS.
Forward feature macros to C and omit NTLM from the feature preview list.
Use the feature macros in source. This ensure that `-V` output matches
the preview.
OpenSSL doesn't support DES when built with `no-des` or `no-deprecated`.
mbedTLS 4.x no longer supports it, and it's possible to disable it in
<4 with `scripts/config.py unset MBEDTLS_DES_C`.
Before this patch this worked for
mbedTLS 4 only, and with a regression for pending PR #16973.
Also:
- drop NTLM feature check from `curl_setup.h` in favour of autotools/
cmake feature macros. This makes `curl_setup.h` no longer need
to include an mbedTLS header, which in turn makes tests/server build
without depending on mbedTLS.
Fixing, in #16973:
```
In file included from tests/server/first.h:40,
from bld/tests/server/servers.c:3:
lib/curl_setup.h:741:10: fatal error: mbedtls/version.h: No such file or directory
741 | #include <mbedtls/version.h>
| ^~~~~~~~~~~~~~~~~~~
```

- move back mbedTLS header include and version check from
`curl_setup.h` to each source which consumes mbedTLS.
- GHA/http3-linux: drop workaround that disabled NTLM for
`no-deprecated` OpenSSL builds.
