[GN]: Enable PCH for WebKit on Mac.

+ Add a new WebKit-level config "mac_precompiled_headers".
+ Add it as a public_config on core:prerequisites since the targets that need it depend on core:prerequisites.
+ Add it as a normal config on :platform since only the target itself needs it, not any deps.
