[clang][Sema] Allow abstract declarators to specify cv-qualified function types as per CWG1417 (#209836)

Abstract declarator contexts (specifically `DeclaratorContext::TypeName`) now properly bypass this restricted rule, allowing cv-qualified function types in `__typeof__` while maintaining restrictions in other contexts like `typeid`, `sizeof`, C-style casts, and `new` expressions per CWG1417.

Outline widenUnitStridedLoadStore helper

Reuses it for both normal and speculative unit-strided memaccesses widening.

Apparently, I misread `createVectorPointer` interface (or maybe it changed
throughout the life of this PR), so this also fixes a bug in the new code.
