Proto2BridgeMessageSet typedef

Proto2BridgeMessageSet = $Shared02

This is proto2's version of MessageSet.

DEPRECATED: DO NOT USE FOR NEW FIELDS. If you are using editions or proto2, please make your own extendable messages for your use case. If you are using proto3, please use Any instead. MessageSet was the implementation of extensions for proto1. When proto2 was introduced, extensions were implemented as a first-class feature. This schema for MessageSet was meant to be a "bridge" solution to migrate MessageSet-bearing messages from proto1 to proto2. This schema has been open-sourced only to facilitate the migration of Google products with MessageSet-bearing messages to open-source environments.

Implementation
