Michael Stapelberg 8878926ea7 internal/impl: fix WhichOneof() to work with synthetic oneofs ... This is the equivalent of CL 638495, but for the Opaque API. While the behavior is the same for non-synthetic oneofs between the Open Struct API and Opaque API, the behavior for synthetic oneofs is not the same: Because the Opaque API uses a bitfield to store presence, we need to use the Opaque presence check in WhichOneof(). This CL extends the testproto generator to use the protoc command-line flag for the test3 testproto (which specifies syntax = "proto3";), as the in-file api_level is only available in .proto files using editions (but editions does not use synthetic oneofs for optional fields, only proto3 does).
