**Is your feature request related to a problem? Please describe.**
We recently added a `-metal` flag to DXC to aid with cross-platform development workflows. When that flag is passed we should set a new preprocessor define in InitPreprocessor (something like `__metal__`) to denote that we're targeting Metal. That will allow for code portability to work around differences in behavior between DX, VK and MTL.
We should ensure this implementation aligns with https://github.com/microsoft/DirectXShaderCompiler/issues/7553.
