[CMake] Tighten ccache settings for prefix headers
https://bugs.webkit.org/show_bug.cgi?id=315410
rdar://177758758
Reviewed by Pascoe.
* Source/cmake/WebKitCCache.cmake: Set CCACHE_PCH_EXTSUM so that
ccache records a checksum when compiling a precompiled header,
and then uses the checksum as the cache key instead of the
contents of the header. Our precompiled headers can be hundreds
of megabytes, so hashing the header text is expensive.
* Source/cmake/WebKitMacros.cmake: Set -fno-pch-timestamp because
by default clang emits a timestamp when compiling a PCH, which
would otherwise force a cache miss.
