add result_adapter into src/tools

result_adapter is chromium-specific tool that reads the test outputs
with gtest/json format and sends them to ResultDB.

It was previously deployed to Swarming bots via pool config, but
this CL adds it to src.DEPS, so that
- swarming pool.cfg no longer have to deploy a chromium specific
cipd pkg, and
- result_adapter becomes available for local runs in dev's workstation.
