IMPALA-4874: Increase the maximum KRPC message size to 4GB

KRPC restricts the maximum message size with --rpc_max_message_size. The
Protobuf API used to deserialize messages also has a maximum size. Both
can be raised, and should be as a stop-gap until Impala has mechanisms
to prevent all its RPC payloads getting too large.

Note that some statestore payloads may still be larger than the 4GB
max. IMPALA-4875 will handle that for the statestore case particularly.

TESTING
-------

* This allows test_very_large_string to pass with KRPC.
* Tests added to statestore-test and rpc-mgr-test for large payloads.
