Add tweak for mingw-w64 when building tests/http/client programs to
avoid a bogus `-Wformat` warning when using mingw-w64 v7.0.0 or older.
The warning is bogus because these programs use curl's `printf()`
implementation that is guaranteed to support that format spec.
Add this for both CMake and autotools. (But only CMake is CI tested with
an old toolchain.)
Apply the workaround to `docs/examples`, and fix an example to use
curl's `printf()` with `CURL_FORMAT_CURL_OFF_T`.
Reintroduce curl `printf()` calls into `tests/http/client`, via #14625.
Also restore large number masks to a printf, changed earlier in #14382.

- extend existing Linux workflow with CMake support.
Including running pytest the first time with CMake.
- cmake: generate `tests/config` and `tests/http/config.ini`.
Required for pytest tests.
Uses basic detection logic. Feel free to take it from here.
Also dump config files in a CI step for debugging purposes.
- cmake: build `tests/http/clients` programs.
- fix portability issues with `tests/http/clients` programs.
Some of them use `getopt()`, which is not supported by MSVC.
Fix the rest to compile in CI (old-mingw-w64, MSVC, Windows).
- GHA/linux: add CMake job matching an existing autotools one.
- GHA/linux: test `-DCURL_LIBCURL_VERSIONED_SYMBOLS=ON`
in the new CMake job.
- reorder testdeps to build server, client tests first and then
libtests and units, to catch errors in the more complex/unique
sources earlier.
- sort list in `tests/http/clients/Makefile.inc`.
Closes#14382
