  [C++20] [Modules] Profile TemplateName by canonical decl

Close https://github.com/llvm/llvm-project/issues/61317

The root cause of the problem is that we profile TemplateName by the
non-canonical decls so that the compiler thought they are two different
types. But this is not true. We fixed the issue after we profile the
template name by using the same name.
