  -----------
  [clang] fix transformation of SubstNonTypeTemplateParmExpr nodes from typealiases and concepts

This makes sure SubstNonTypeTemplateParmExpr produced from non-specialization
decls (Type alias templates and concepts) are correctly transformed.

This makes the SubstNonTypeTemplateParmExpr store the parameter type directly,
and uses that instead of relying on the AssociatedDecl.

Fixes #191738
Fixes #196375
