Refactor incident_helper to use protoutil and cppstream plugin.

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.
