Revert 277208 "[PPAPI] Compositor API implementation."

This CL seems to cause perf bot failure.
The log said nacl_helper-data size gained exceeds expectation.

PTL later.

I think you can just reland the CL and update the size expectation.

How do I update the size expectation? Or just reland the CL?

Sorry for late follow up.
The instruction is available on "Handle sizes regressions" in
http://www.chromium.org/developers/tree-sheriffs/perf-sheriffs

For your case, (1) reland your CL, (2) update "reva" and "revb" in
tools/perf_expectations/perf_expectations.json, (3) run make_expectations.py,
(4) upload, get reviewed and land the expectation update.
