It is very unlikely the protobuf changes the value in descriptor.h,
and if defines an extra mapping, there are several places to maintain:
1. java-stream,
2. cpp-stream,
3. ProtoOutputStream.java
4. ProtoOutputStream.cpp
5. Privacy.h (GetFieldId)
6. StatsLog to generate field id (type << 32 + field number)
Therefore use the current value in descriptor.h seems reasonable unless
they change that, very very unlikely, they probably will just add new
types, and deprect the existing ones like Group.

1. Split the parsers to its own file to prevent all the parsers in one
gaint file.
2. Completely get rid of protobuf-cpp-full in incident_helper, use
ProtoOutputStream and cppstream instead, the incident_helper binary is
reduced from ~500K to ~113K.
3. Write data to protobuf even its values are zero/default, the reason
is for example we have a repeated int32 orders = 1; and people
explicitly append 0 so the total repeated field has 10 values, if zero
is not written to serialized data, this repeated field will only have 9
values which is not what we want at first place. This also aligns with
the default protobuf serialization behavior in incident_helper_test.
4. Use Android.bp for protoutil lib since it is not able to depend on
libs compiled by .mk file, it works the other way.
5. Add a new custom message option for streaming_proto, if specified,
the cppstream will create extra metadata to get field ids by field name.
A Table class is created in incident_helper to use it.

Test: unit tested as well as on device test

It is very similiar to protoc-gen-javastream, which generates field Ids used
by ProtoOutputStream.cpp to dump protobuf data.

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
