[clang] Make handling of unnamed template params similar to function params
Summary:
Clang uses the location identifier should be inserted for declarator
decls when a decl is unnamed. But for type template and template template
paramaters it uses the location of "typename/class" keyword, which makes it hard
for tooling to insert/change parameter names.
This change tries to unify these two cases by making template parameter
parsing and sourcerange operations similar to function params/declarator decls.
