- set `CARES_NO_DEPRECATED` to avoid c-ares deprecation warnings.
Like autotools does.
- drop unused c-ares header directory when building libtests and test
servers.
- disable TrackMemory (aka `CURLDEBUG`) feature for MSVC builds.
It fails on test 558 and 1330, saying that TrackMemory isn't working.
Left a FIXME about it.
- GHA/macos: enable c-ares in a cmake job.
- GHA/windows: enable c-ares in MSVC job.
Fixes#14202
- GHA/windows: add c-ares mingw autotools job with tests.
(move `--with-windows-unicode` option from 'default' job to
this one to keep the former "default".)
Put these tests on ignore for now:
```
FAIL 472: 'aws-sigv4 with query' HTTP, aws-sigv4
FAIL 1299: 'Send "OPTIONS *" with --request-target' HTTP, --request-target
FAIL 1613: 'Send "OPTIONS *" with --request-target to a proxy' HTTP, HTTP proxy, --request-target
```
Ref: https://github.com/curl/curl/actions/runs/10388126947/job/28765761441#step:15:5902
472: fails with mingw despite Unicode enabled.
1299, 1613: seem like a case of expanding '*' to a filename.
- GHA/windows: enable c-ares in mingw cmake job.
Closes#14541
