    update slobs to build on macOS Tahoe dev env (#676)

    * cmake: Disable CCache for local builds and enable by default for CI

    * cmake: Disable discovery of Homebrew libraries for dependencies

    macOS builds should only use dependencies built via the obs-deps
    build scripts. Default variants of the same dependencies are not
    compatible with our app packaging requirements and thus will create
    issues when creating the app bundle.

    This is specifically an issue when MbedTLS is installed via Homebrew
    which ships a CMake package config by default and is picked up
    by our code ever since we switched to prefer CMake packages.

    * upgrade Qt6 to resolve missing AGL framework on macos Tahoe

    * Apple remove AGL framework on macos tahoe which breaks the older Qt6
