Why are these changes needed?
#39419 upgraded grpc, absl and protobuf to fix a memory leak but it turned out to have perf regression.
GRPC 1.50.2, protobuf 21.6, absl 2022062.1 have the memory leak but no perf regression so we downgrade to these versions.
All the changes we made to upgrade to 1.57.0 are still needed.
