[clang] NFCI: use TemplateArgumentLoc for type-param DefaultArgument (#92854)
This is an enabler for a future patch. This allows an type-parameter default argument to be set as an arbitrary TemplateArgument, not just a type. This allows template parameter packs to have default arguments in the AST, even though the language proper doesn't support the syntax for it. This will be used in a later patch which synthesizes template parameter lists with arbitrary default arguments taken from template specializations. There are a few places we used SubsType, because we only had a type, now we use SubstTemplateArgument. SubstTemplateArgument was missing arguments for setting Instantiation location and entity names. Adding those is needed so we don't regress in diagnostics.
