In this CL, we update generated_message_tctable_lite to support both length-prefixed and delimited when it comes to parsing submessages.
In the past, the parser would do error checking based on the schema. If a .proto file declared a submessage to be length-prefixed but an SGROUP was encountered on the wire, it would invoke the fallback. This behavior is now updated: the parser will solely look at the tag when dealing with submessages.
This increases the flexibility of the parser and will make our Editions rollout smoother.
