Pepper: Remove in-process support for PPB_Audio.

This is the first in a series of changes to refactor support for PPB_Audio. We
don't need in-process support, so this gets the support for that out of the way
in a change that can be easily reverted if necessary.

cc: Unified the implementation of running tasks on origin and worker threads.

RasterWorkerPoolTaskImpl::RunOnWorkerThread and RasterWorkerPoolTaskImpl::RunOnOriginThread are very similar now. The only difference is we do not need to clone the picture-pile when running on origin thread. This will need to be revisited when we actually turn on hybrid or multi-threaded rasterization. I also moved push-pop GL marker to DirectRasterWorkerPool, which removed the dependency of RasterWorkerPoolTaskImpl on ContextProvider.

Reduce number of policies per PolicyPrefIndicatorTest

Each PolicyPrefIndicatorTest instantiation tests a chunk of policies. The
chunk size is 50 policies right now. This works well everywhere except
for the Windows debug bots, which are very slow and are running into
timeouts after testing as few as 13 policies.

This CL reduces the chunk size to 10 policies.
