  [SemaHLSL] Warn when a local resource is re-assigned to non-unique global resource (#182101)

Generate a warning whenever a local resource is (re-)assigned such that
it is not guaranteed to map to a single unique global resource.

An error is not generated during sema because simple DCE or constant
folding might resolve the assignment to be to a unique global resource.
Instead, an error will be reported when trying to resolve the resource
access in the `dxil-resource-access` pass, implemented
[here](https://github.com/llvm/llvm-project/pull/182106).

Resolves https://github.com/llvm/llvm-project/issues/179303.
