Windows: Add sccache support.
sccache [1] is one of the few ccache like solutions that will work on windows. sccache support can be enabled with the `WITH_WINDOWS_SCCACHE` cmake option however it will only will work with ninja as the build system, msbuild is not supported currently. Advanced option, developes are expected to obtain and configure sccache on their own. ``` Full build no cache 1428.90s (100.00%) Full build cached 434.34s ( 30.40%) ``` [1] https://github.com/mozilla/sccache Reviewed By: nicholas_rishel, Brecht Differential Revision: https://developer.blender.org/D7466
