Integrate support for sccache into the build system. This allows us to get a reasonable performance increase for clean builds for the C/C++ side of the build. This is currently limited to the MSVC compiler as the extended compiler flags cause issues for sccache.

Is the removal of debug builds related here? sccache should see the flag in the compiler invocation and realize that it's a different object being emitted.

Yes, it is related. The Swift build system is just not able to support this (sccache + PDBs don't work very well together, the other changes to use the embedded debug is related). Once we upgrade to a reasonable version of CMake, we should be able to use the CMAKE_MSVC_DEBUG_INFORMATION_FORMAT=Embedded and get the build types to work again.
