Followup to D134378 <https://reviews.llvm.org/D134378>.
With PrintingPolicy::SuppressScope, we'd also not print the scope in template
params. The intention was only to skip the scope for the class because we
expect template params to be fully qualified when comparing them for simple
template names.
Add a PrintingPolicy::NoSuppressTemplateParamsScope which disables
SuppressScope for template params.
