[Clang][NFC] Rename UnqualPtrTy to DefaultPtrTy (#163207)

`UnqualPtrTy` didn't always match `llvm::PointerType::getUnqual`:
sometimes it returned a pointer that is not in address space 0 (notably
for SPIRV).

Since `UnqualPtrTy` was used as the "generic" or "default" pointer type,
this patch renames it to `DefaultPtrTy` to avoid confusion with LLVM's
`PointerType::getUnqual`.
