Implement HLSLElementwiseCast excluding support for splat cases Do not support casting types that contain bitfields. Partly closes https://github.com/llvm/llvm-project/issues/100609 and partly closes https://github.com/llvm/llvm-project/issues/100619 Re-land #118842 after fixing warning as an error, found by a buildbot.
