build: enable -Wformat-signedness, fix issues found
Adjust code to avoid `-Wformat-signedness` warnings, while making sure
that enums are always cast to a known type when passing them to `printf`
functions, to support compilers and compiler settings where enums are
not default-size signed ints.

- cast integers printed as hex to `unsigned`. (63 times, 20 of them in
  `mbedtls.c`)
- cast misc enums to `int` for printing. (31 times)
- cast `CURL_LOCK_DATA_*` enums to `int`. (4 times)
- cast `CURL_FORMADD_*` enums to `int`. (13 times)
- cast `CURLSHE_*` enums to `int`. (3 times)
- cast `CURLUE_*` enums to `int`. (33 times)
- cast `CURLMSG_*` enums to `int`. (6 times)
- cast `CURLE_*` enums to `int`. (~380 times)
- unit1675: fix mask.

ngtcp2: share common functionality
Share common functions/structs between ngtcp2 HTTP/3 and the proxy
version.

Fix bugs in proxy implementation when it comes to stream and pollset
handling and transfer lifetimes.

Curl_multi_xfer_sockbuf_borrow: work without multi

When a connection gets shutdown by a share, the easy handle used is
share->admin and it does not have a multi handle. In that case let
Curl_multi_xfer_sockbuf_borrow() allocate a buffer to be freed on
release.

This happens when a TLS filter sends its last notify through a HTTP/3
proxy tunnel.

chunked: reject invalid bytes in trailer
Trailers are delivered to the application as headers via
CLIENTWRITE_TRAILER, but unlike regular response headers they skipped
the verify_header() checks, so a server could smuggle a nul byte (or
stray CR) into a header reaching CURLOPT_HEADERFUNCTION and
curl_easy_header().

Run each assembled trailer line through Curl_verify_header(), the same
validation used for normal headers.

Covered by the new test 2106.

ssl native_ca_store: always reinit
Add bit `native_ca_store_opt` to keep the setting of

progress: fx CURLINFO time reporting
Whack the times reported for a transfer (see
https://curl.se/libcurl/c/curl_easy_getinfo.html#TIMES) into order for
all variations of up-/download, http/ftp etc. Make sure they are
reported in the documented order.

There is still the *possibility* of PRETRANSFER being longer then
POSTTRANSFER, if a server sends a response before an upload is done.
POST is the time the first response byte is received, and PRE is the
time the last byte was sent by curl.

This may happen with more likelihood on HTTP/2 and 3 for a server
rejected upload. But for successful uploads, the answer will almost over
come afterwards.

Undo the previous twists in lib500.c tests, adjust pytest timeline
checks.
