  -----------
  [clang] NNS: don't print trailing scope resolution operator in diagnostics (#130529)

This clears up the printing of a NestedNameSpecifier so a trailing '::'
is not printed, unless it refers into the global scope.

This fixes a bunch of diagnostics where the trailing :: was awkward.
This also prints the NNS quoted consistenty.

There is a drive-by improvement to error recovery, where now we print
the actual type instead of `<dependent type>`.

This will clear up further uses of NNS printing in further patches.
