Stop generating data-source specific C++ classes in tracing/core
We generate C++ classes from proto for a bunch of core classes
like DataSourceConfig, DataSourceDescriptor etc. This is to
prevent spreading protobuf dependencies all over the places.
However, at some point in the past we started adding data-source
specific sub-messages to DataSourceConfig and doing to required
to generate C++ classes for things that don't really belong to
tracing/core (e.g. FtraceConfig, SysStatsConfig, etc).
This CL introduces a decoupling using a proto annotation [lazy=true].
When fields are annotated as such, the generated C++ stub exposes
the field as a raw byte array. This allows to break the dependency
between tracing/core and those configs and pushes the decoding
responsibility to the actual data sources.
This is a step towards getting rid of libprotobuf dependencies
in tracing/core for the client library.
Note that at the moment the generated classes still depend on
libprotobuf for the FromProto / ToProto conversions.
