cmake: untangle feature detection interdependencies

- reduce `check_include_file_concat()` use to those headers that either
depend on a previously detected header, or another header or symbol
detection depend on it.

- replace `check_symbol_exists()` with `check_function_exists()` for
functions that are detected with `AC_CHECK_FUNCS()` in `./configure`.
This makes `setmode()` no longer be detected with MSYS, syncing
this with `./configure`. Instead `_setmode()` is used now also in
CMake MSYS builds. This is consistent with Cygwin builds also.

- add comment about which header/symbol detection depends on what
header. Based on `./configure` mainly.

- form `CURL_TEST_DEFINES` manually, and include only those macros which
are actually used in `CMake/CurlTests.c`.

- change `curl_internal_test()` to use `CMAKE_REQUIRED_DEFINITIONS`,
instead of `CMAKE_REQUIRED_FLAGS` to simplify the logic, and to allow
dropping the latter macro completely.

- drop `windows.h` from header and symbol checks.

- `./configure`: add comment about whether `netinet/in6.h`, `sys/un.h`
are indeed meant to be included for all detections. There is a chance
they were added there by accident.

Detection resuls were cross-checked between
436bbbe7abebf0ee3a2b0bfb3ec5db7ce8c8db4c (master) and
48ff4694e608ccfdedf7ce5bab2b96d6b2c23cda (this PR), for CI GHA Linux,

TLS: TLSv1.3 earlydata support for curl

Based on #14135, implement TLSv1.3 earlydata support for the curl
command line, libcurl and its implementation in GnuTLS.

If a known TLS session announces early data support, and the feature is
enabled *and* it is not a "connect-only" transfer, delay the TLS
handshake until the first request is being sent.

- Add --tls-earldata as new boolean command line option for curl.
- Add CURLSSLOPT_EARLYDATA to libcurl to enable use of the feature.
- Add CURLINFO_EARLYDATA_SENT_T to libcurl, reporting the amount of
bytes sent and accepted/rejected by the server.

Implementation details:
- store the ALPN protocol selected at the SSL session.
- When reusing the session and enabling earlydata, use exactly
that ALPN protocol for negoptiation with the server. When the
sessions ALPN does not match the connections ALPN, earlydata
will not be enabled.
- Check that the server selected the correct ALPN protocol for
an earlydata connect. If the server does not confirm or reports
something different, the connect fails.
- HTTP/2: delay sending the initial SETTINGS frames during connect,
if not connect-only.

Verification:
- add test_02_32 to verify earlydata GET with nghttpx.
- add test_07_70 to verify earlydata PUT with nghttpx.
- add support in 'hx-download', 'hx-upload' clients for the feature

cmake: replace `check_include_file_concat()` for LDAP and GSS detection

Replace `check_include_file_concat()` with `check_include_file()` in
GSS/LDAP detection to avoid these headers spilling into subsequent
feature checks.

- For LDAP, reverse detection order to match with `./configure`.
Though, in current LDAP packages `ldap.h` does include `lber.h`.

- For GSS, align header detection logic with `./configure`, where
`gssapi/gssapi_generic.h` might require `gssapi/gssapi.h`, and
`gssapi/gssapi_krb5.h` might require both.

cmake: stop adding dependency headers to global `CMAKE_REQUIRED_INCLUDES`

It was done for `zlib`, `brotli`, `libpsl`, `libssh2`, `wolfssh`
(a copy-paste case for `wolfssh`).

Feature detections should not rely by default on dependency headers.
There is no evidence they do now. If it becomes necessary, headers
should added for the duration of the feature check.

cmake: add native `pkg-config` detection for mbedTLS, MSH3, Quiche, Rustls, wolfSSL

Also:
- detect and add required system libraries for Rustls on macOS and
non-Windows.
- add Linux CMake jobs for the touched dependencies.
Caveats:
- MSH3 generates a broken `libmsh3.pc`, so needs manual config.
Upstream PR: https://github.com/nibanks/msh3/pull/225
- Rustls `.pc` file missing, so needs manual config.

An internal change worthy of mention is that we are using the lib path
and name information returned by `pkg-config` as-is. Meaning the libname
doesn't include the full path, like it's usual with native cmake
detection. The path comes separately and needs to be rolled separately.
For this we add it to targets via `link_directories()`. We also keep tab
of them in `CURL_LIBDIRS` and use that in `libcurl.pc`. Feature checks
also need to receive these paths. CMake doesn't offer
a `CMAKE_REQUIRED_*` variable for this purpose, only
a `CMAKE_REQUIRED_LINK_OPTIONS` accepting raw linker flags. Add a macro
to convert a list of paths to linker options to solve it. wolfSSL
requires this for now.
