It is very similiar to protoc-gen-javastream, which generates field Ids used
by ProtoOutputStream.cpp to dump protobuf data.
Bug: 65641021
Test: compile the streaming_proto:
$ mmm -j frameworks/base/tools/streaming_proto/
and run:
$ PATH=$PATH:out/host/linux-x86/bin/protoc-gen-cppstream aprotoc
--cppstream_out=tmp/
frameworks/base/core/proto/android/service/procstats.proto
frameworks/base/core/proto/android/util/common.proto

The classes there add a way for the platform to write out
protocol buffers that doesn't require lots of small objects,
generate code, and extra copying.
Includes the plugin for protoc to generate the constants.
Test: proto cts tests
