  [Concepts] Fix isDeclarationSpecifier to detect type-constraints correctly

isDeclarationSpecifiers did not handle some cases of placeholder-type-specifiers with
type-constraints, causing parsing bugs in abbreviated constructor templates.

Add comprehensive handling of type-constraints to isDeclarationSpecifier.

(cherry picked from commit b7ce85a130789d23c69156f4b899962458d1f05d)
