  -----------
  Keep inherited dllimport/export attrs for explicit specialization of class template member functions

Previously we were stripping these normally inherited attributes during
explicit specialization. However for class template member functions
(but not function templates), MSVC keeps the attribute.

This makes Clang match that behavior, and fixes GitHub issue #54717
