[clang] [HLSL] Add HLSLAttributedResourceType (PR #106181)

I think this looks basically reasonable, though some parts are a bit hard to decipher without the actual attributed types present yet. We probably need someone familar with the clang AST, Sema, and serialization to take a look as well - maybe @AaronBallman?
