Upgrade Protobuf Java to 3.22.3 (aka 22.3)

The version used by protoc-gen-grpc-java will be upgraded separately,
because of large C++ build changes necessary. But that won't impact
users at all. We are upgrading to protoc 22.3; only the grpc plugin is
not upgraded.

Bazel is upgraded for both Java and C++.
