[Mike Hommey [:glandium]]

Attachment: Bug 1857400 - Use CMAKE_MSVC_RUNTIME_LIBRARY instead of LLVM_USE_CRT_RELEASE.

The latter was deprecated in
https://github.com/llvm/llvm-project/commit/c6bd873403a8ac6538a3fe3b3c2fe39c16b146a6
and removed more recently in
https://github.com/llvm/llvm-project/commit/618e5d2c2d8e0c288c37b883ece553ca4f994c2e

Fortunately, the former is works with LLVM 17, so we don't need to
special case, we can use the same as for trunk.
