clang: build a smaller clang/llvm

Msys2 builds pretty versatile Clang and LLVM packages with LLVM backends to cross compile for various target architectures. That comes at the cost of big binaries, that challenge how we manage the Git for Windows SDK[1]. But for Git ffor Windows we don't need all of this. We only need a Clang that can compile ARM64 binaries on ARM64. [1] git-for-windows/git-sdk-arm64#7 Signed-off-by: Matthias Aßhauer <[email protected]>
