Improve CI cache usage (#6868)

* Update third-party actions to latest version

* Use vcpkg in manifest mode

* Only trim ccache after build

* Use ccache with MSVC

* Use Brewfile and cache Homebrew downloads

* Use --print-config for ccache 3

* Attempt to make ccache actually work with MSVC

* Zero ccache stats before building

* Use SDL2 on macOS
