TEZ-4715: Migrate Tez PB Protocols from ProtobufRPCEngine to ProtobufRPCEngine2

[Aggarwal-Raghav]

1. Migrated Protobuf imports from com.google.protobuf to shaded org.apache.hadoop.thirdparty.protobuf
2. Added hadoop-thirdparty dependency (v1.4.0) to the root POM to ensure Hadoop 3.4.2 compatibility. This will be updated for every hadoop version upgrade. For now I have kept proto version to 3.25.5 as it was in tez and will be in-sync with hadoop-3.5.0
3. Used maven-replacer-plugin (same as hadoop) to automated package refactoring in generated proto code.

(!) A patch to the testing environment has been detected.
Re-executing against the patched versions to perform further tests.
The console is at https://ci-hadoop.apache.org/job/tez-multibranch/job/PR-493/1/console in case of problems.

The UT failure debugging in #483 (comment) requires hadoop thirdparty making this PR dependent.

TEZ-4715 + TEZ-4708 will completely migrate tez from WritableRPCEngine + ProtobufRPCEngine => ProtobufRPCEngine2

@abstractdog From the code point of view, this seems right, We had to just use the RPCEngine2 & migrate to the Hadoop Thirdparty. That is rightly done here.

But I think this would be an incompatible change, beyond this point I believe Hive master won't build nor work with Tez master. Hive has to do the same activity when moving to Tez-1.0.0 & that would be incompatible for Hive as well & believe the older Hadoop versions won't work post this activity in Hive or Tez, unless there was something done later to fix it, which I don't think...

There were compat issues that is why I believe HADOOP-17046 was done later to make sure older client can work with them. Means protobuf is indeed a very known heavy Incompat change, a lot of discussion at HADOOP-13363, in case interested.

These are the tradeoffs, I just wanted to highlight. Rest all cool
