  [llvm] Build Windows release package with clang-cl if possible (#135446)

If `clang-cl.exe` and `lld-link.exe` are installed in `%PATH%`, the
Windows release build script will now use these by default, in place of
MSVC. The reason for doing this is that MSVC still has, for the past
year(s), a O(N^2) behavior when building certain LLVM source files,
which leads to long build times (minutes per file). A report was filled
here:
https://developercommunity.visualstudio.com/t/ON2-in-SparseBitVectorBase-when-com/10657991

Also added a `--force-msvc` option to the script, to use MSVC even if
clang-cl is installed.
