  -----------
  [clang] don't print redundant context notes when instantiating alias templates

The redundant notes were introduced with the workaround for finding
the template instantiationa args for lambdas inside template type aliases.

This removes the notes for the cases where we are simply instantiating an
outer template, and when diagnosing uses of the alias template.

Also adds comments calling the workaround explicitly.
