Add support for new v8 data source

We are planning to add a new data source for the v8 Javascript engine.
V8 emits an event every time a new code snippet is generated. These
events hold enough information to be able to symbolize stack frames
during ingestion.

This patch introduces a new top level trace proto to emit said new code
events.
