a6419105 - [clang][CGObjC] Remove unused ExternalProtocolPtrTy (NFC) (#133870)

[clang][CGObjC] Remove unused ExternalProtocolPtrTy (NFC) (#133870) This function was previously used to get a type to the protocol that was used to bitcast the initializer of GenerateProtocol. This bitcast has later been removed (thanks to opaque pointers), but the member was left behind. History: - 020de3254acc3 used ExternalProtocolPtrTy - 34ee69b4ce662 removes the bitcast Also technically part of #123569
