cmake: leave the timestamp out of precompiled headers on clang (#28816)

Clang stores the modification time of the precompiled header sources
inside the header and refuses the header when they differ. A cached
header restored from another checkout carries the timestamps of that
checkout, so the build fails. The option covers the compilers ccache
treats as MSVC while they are clang underneath, clang-cl and the Intel
LLVM drivers.
