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.
  ```
  ./curl/lib/mqtt.c: In function 'mqtt_doing':
  ./curl/lib/mqtt.c:746:17: error: declaration of 'byte' shadows a global declaration [-Werror=shadow]
    746 |   unsigned char byte;
        |                 ^~~~
  /opt/homebrew/Cellar/wolfssl/5.7.0_1/include/wolfssl/wolfcrypt/types.h:85:36: note: shadowed declaration is here
     85 |             typedef unsigned char  byte;
        |                                    ^~~~
  ```

- format `FindWolfSSL.cmake` closer to neighbours.
