explicitly check also for -fno-pch-codegen

The catch is that clang-cl does not know it, it only understands
-Xclang -fpch-codegen. On Linux -fno-pch-codegen is handled by
the driver, but clang-cl doesn't know the options, so we pass
to the backend using -Xclang, but that one understands only
-fpch-codegen. So if not found, do not use that option, the cost
is only that compiling precompiled_skia.cxx will take longer.
