There are currently no diagnostics being emitted for when a resource is bound to a register with an incorrect binding type prefix. For example, a CBuffer type resource should be bound with a a binding type prefix of 'b', but if instead the prefix is 'u', no errors will be emitted. This PR implements such diagnostics. The focus of this PR is to implement both the flag setting and diagnostic emisison steps specified in the relevant spec: https://github.com/microsoft/hlsl-specs/pull/230 The relevant issue is: https://github.com/llvm/llvm-project/issues/57886 This is a continuation / refresh of this PR: https://github.com/llvm/llvm-project/pull/87578
