  [Clang] Ignore empty FieldDecls when asking for the field number (#100040)

A FieldDecl that's an empty struct may not show up in CGRecordLayout. Go
ahead and ignore such a field as it shouldn't make a difference to these
calculations.

Fixes: 1f6f97e2b64a ("[Clang] Loop over FieldDecls instead of all Decls (#99574)")
