[gn build] Bump macOS target to 12 and make it configurable (#107492)

Browse Source 
Bumping the deployment target from macOS 10.10 to 12 enables chained
fixups and DWARF 4 debug information for the LLVM binaries and
libraries.
    
Like in Chromium, a GN arg (`mac_deployment_target`) is added to allow
overriding the default.
