- adds the Perfetto repository, build rules to build the config proto and trace processor along with its dependency sqlite.
- adds some of the scaffolding for taking a Perfetto trace in GAPIS (not yet exposed to the GAPIS API, though)
- adds support for opening a Perfetto trace in GAPIS via the API
- adds a GAPIS API to run queries against a Perfetto trace

Eww this is an ugly API.
virtual bool Parse(std::unique_ptr<uint8_t[]>, size_t) = 0;
You will need the copy unless we can allocate the data with new but I think this is meant to be exported to go, so the data is coming from "magic place"

Is this the path on the Android device where we are putting the trace?

Any way we can check this at build-time?
