Merge #120: cmake, ci: Ccache improving in macOS jobs

326d0f7 fixup! ci: Test CMake edge cases (Hennadii Stepanov)

Pull request description:

  For the recent two consequential CI runs:
  - https://github.com/hebasto/bitcoin/actions/runs/8263699604 and
  - https://github.com/hebasto/bitcoin/actions/runs/8264179478

  I've noticed a [pure Ccache performance](https://github.com/hebasto/bitcoin/actions/runs/8264179478/job/22607226576) for the "macOS 13 native, x86_64, Xcode 14.3" job:
  ```
  Cacheable calls:     634 / 634 (100.0%)
    Hits:                0 / 634 ( 0.00%)
  ```

  This PR sets `CCACHE_COMPILERCHECK=%compiler% -v` for macOS jobs to avoid false cache invalidating.

  The other option, i.e., `content`, has been tried as well in my experiments, but it also has cache performance issues.
