[DebugInfo] Emit DW_TAG_enumeration_type for referenced global enumerator. This essentially reverts changes from r361400 while keeping behavior for CodeView.

[DebugInfo] Use per-enumerator signedness for DIEnumerator Allegedly the DWARF backend ignores this field of DIEnumerator, but we set it nonetheless in case we decide to use it in the future. Alternatively, we could remove it, but it is simpler to pass down the signed bit as it is in the AST for now. Implemented to address comments on D106585
