  [HLSL] Collect explicit resource binding information (#111203)

Scans each global variable declaration and its members and collects all
required resource bindings in a new `SemaHLSL` data member `Bindings`.

New fields are added `HLSLResourceBindingAttr` for storing processed
binding information so that it can be used by CodeGen (`Bindings` or any
other Sema information is not accessible from CodeGen.)

Adjusts the existing register binding attribute handling and diagnostics
to:
- do not create HLSLResourceBindingAttribute if it is not valid
- diagnose only the simple/local errors when a register binding
attribute is parsed
- additional diagnostic of binding type mismatches is done later and
uses the new `Bindings` data

Fixes #110719
