cmake: tidy up more in Find modules
- add `NAMES` where missing.
- document input variables (including deprecated ones.)
- comment cleanups.
- FindWolfSSL: drop stray `QUIET` from `pkg_check_modules()`.
  (`QUIET` may be re-added for all modules in the future.)

Closes #14579

cmake: tidy up around ngtcp2 and wolfSSL
- fix to add the `m` library without path.
  Follow-up to 8577f4ca08 #14343
  Authored-by: Tal Regev
  Fixes #14549

- move `m` library detection to wolfSSL Find module.
  `m` is necessary for wolfSSL (wolfcrypt) library functions called by
  `libngtcp2_crypto_wolfssl`.
  Follow-up to 8577f4ca08 #14343

- fix comment header about supported `COMPONENT` names.

- quote strings.

- lowercase local variables.

cmake: do not unset the deprecated mixed-case variables
To avoid interference with the calling env.

(Keep unsetting for the DIRS/DIR cases in BearSSL and mbedTLS, because
the deprecated variables play a new role in the detection.)

cmake: rename wolfSSL and zstd config variables to uppercase
To match with other config variables and other projects.

Rename these CMake configuration variables:
- `WolfSSL_INCLUDE_DIR` -> `WOLFSSL_INCLUDE_DIR`
- `WolfSSL_LIBRARY`     -> `WOLFSSL_LIBRARY`
- `Zstd_INCLUDE_DIR`    -> `ZSTD_INCLUDE_DIR`
- `Zstd_LIBRARY`        -> `ZSTD_LIBRARY`

The old values continue to work, with a warning suggesting the new name.

Also:
- add similar warnings for earlier renames for mbedTLS and BearSSL.
- rename internal variables `PC_Zstd_*` to uppercase.

cmake: sync up version detection in Find modules
- use the same pattern across all Find modules:
  - verify if the version header exists before reading it.
  - use a single regex per lookup.
  - sync regexes between Find modules.
  - use generic temporary variable names.
  - improve readability.
  - make it simpler to transition to new CMake syntax in the future:
    ```cmake
    file(STRINGS "${CARES_INCLUDE_DIR}/ares_version.h" _version_str REGEX "<...>")
    unset(_version_str)
    set(CARES_VERSION "${CMAKE_MATCH_1}")
    ```
    Ref: https://cmake.org/cmake/help/latest/policy/CMP0159.html#policy:CMP0159

- fix zstd version detection to be CMake 3.7 compatible.
  Required 3.9 before this patch, for the `CMAKE_MATCH_<n>` feature.

cmake: revert to pkg_check_modules()
Prefer `pkg_check_modules()` over `pkg_search_module()`.

`pkg_check_modules()` logs a line when there is a hit, and also warnings
if a sub-dependency is missing. In `QUIET` mode, both are silent.

The extra info is useful to see if a detection happened via
`pkg-config`.

Keep `pkg_search_module()` in `FindGSS`. We pass two dependencies
there and we want to keep stopping on the first one.

Partially reverts c2889a7b41 #14388

cmake: add missing version detection to Find modules
- use `pkg-config` version when available and where it wasn't yet used.

- add manual version detection for dependencies where this is possible
  (via a public header) and where it wasn't done yet.

cmake: tidy up Find modules
Smoothen out minor differences between Find modules.

- brotli, nghttp2: drop redundant `FOUND_VAR` specifiers from
  `find_package_handle_standard_args()` calls.
  This function sets both `<NAME_UPPER>_FOUND` and `<NAME>_FOUND`
  by default.

- brotli: set result vars only when found.

- brotli: add missing `mark_as_advanced()` call.

- brotli: delete custom fail message.

- mbedtls, bearssl: use `REQUIRED_VARS` instead of `DEFAULT_MSG`.

- msh3, quiche: set `<NAME>_VERSION` (via pkg-config).

- wolfssl: also use `PC_WOLFSSL_INCLUDEDIR`, `PC_WOLFSSL_LIBDIR`
  as hints.

- libpsl, libssh2, zstd: clear temporary variables used for version
  detection.

- gss, msh3, nghttp2, nghttp3, ngtcp2, quiche, zstd: fix to apply
  `mark_as_advanced()` to internal variables only.

cmake: add CURL_USE_PKGCONFIG option
Add option to control whether to use `pkg-config` to detect
dependencies. Curl's CMake uses `pkg-config` by default for all targets
except for MSVC without vcpkg.

With the CMake option `-DCURL_USE_PKGCONFIG=ON` you can override it to
use `pkg-config` always.

If `pkg-config` is causing issues, e.g. in cross-builds or other cases,
`-DCURL_USE_PKGCONFIG=OFF` disables all use of `pkg-config`.

Also add it to `curl-config.cmake`. Not yet used, but will be once curl
starts referencing any curl-specific `Find*` module from this public
script.

cmake: allow pkg-config in more envs
Before this patch, `pkg-config` was used for `UNIX` builds only (with
a few exceptions like wolfSSL, libssh, gsasl, libuv). This patch extends
`pkg-config` use to all envs except: `MSVC` without vcpkg. Meaning MSVC
with vcpkg will now use it. Also mingw on Windows.

Also apply the new condition to options where `pkg-config` was used
unconditionally (= for all targets). These are:
`-DCURL_USE_WOLFSSL=ON`, `-DCURL_USE_LIBSSH=ON`,
`-DCURL_USE_GSASL=ON` and `-DCURL_USE_LIBUV=ON`

This patch may still cause regressions for cross-builds (e.g. mingw
cross-build from Unix) and potentially other cases. If that happens, we
recommend using some of these methods to explicitly disable `pkg-config`
when using CMake:
- CMake option: `-DPKG_CONFIG_EXECUTABLE=`
  (or `-DPKG_CONFIG_EXECUTABLE=nonexistent` or similar)
  This is similar to the (curl-specific) `PKG_CONFIG` env for autotools.
- export env: `PKG_CONFIG_LIBDIR=`
  (or `PKG_CONFIG_PATH`, `PKG_CONFIG_SYSROOT_DIR`,
  or the CMake-specific `PKG_CONFIG`)

We may improve control over this in a future patch, also allowing opting
in MSVC (without vcpkg).

cmake: more syntax tidy-up
- quote string literals.
  In the hope it improves syntax-highlighting and readability.

- use lowercase, underscore-prefixed local var names.
  As a hint for scope, to help readability.

- prefer `pkg_search_module` (over `pkg_check_modules`).
  They are the same, but `pkg_search_module` stops searching
  at the first hit.

- more `IN LISTS` in `foreach()`.

- OtherTests.cmake: clear `CMAKE_EXTRA_INCLUDE_FILES` after use.

- add `PROJECT_LABEL` for http/client and unit test targets.

- sync `Find*` module comments and formatting.

- drop a few local variables.

- drop bogus `CARES_LIBRARIES` from comment.

- unquote numeric literal.

cmake: improve wolfSSL detection
- support detecting wolfSSL via pkg-config (like autotools.)

- detect wolfSSL version.

- detect `HAVE_WOLFSSL_DES_ECB_ENCRYPT`.
  (needs e.g. `--enable-curl` when building wolfSSL)

- detect `HAVE_WOLFSSL_FULL_BIO` and enable HTTPS-proxy feature.
  (needs e.g. `--enable-opensslall` when building wolfSSL)

- fix to show `HTTPS-proxy` in cmake feature list.
  Ref: 55807e6c05 #9962

- fix to show `NTLM` in cmake feature list.

- fix to show `smb` and `smbs` in cmake protocol list.

- add wolfSSL CMake job to GHA (for macOS).

- fix mqtt and wolfSSL symbol clash.
  ```

- format `FindWolfSSL.cmake` closer to neighbours.
