This patch ensures that picture pile base is thread safe, since it is
not guaranteed that the ref is always adjusted on the same thread. In
particular, the worker thread (which refs picture pile on the cc thread)
might deref it (and delete it) on the worker thread.

Allocation of GpuMemoryBuffers requires a round-trip to the browser
process and by moving this to worker threads it is no longer on
the critical path on the compositor.

The LockForWrite mechanism in the ResourceProvider has been
adjusted to properly support worker thread allocation of
resources.

We currently null the twin_layer_ pointer when pushing to the active
tree and then using hashmap lookups to find the recycled twin, and
reconnecting the pointers in DoPostCommitInitializationIfNeeded().

Instead, we can leave the pointers always valid and use Getter methods
that check what tree the twin is on to decide if we should consider it
a pending twin or a recycle twin.

This means that during commit the pending layer will be able to find
its active twin when it updates its picture pile, so that it can share
tiles that are not invalidated. (Previously it wouldn't know about its
twin until after commit, when we set it up and then did SyncTilings.)
This allows us to have a more straightforward flow of data, setting up
the pending tilings when we give it a pile from the main thread
instead of doing it at some hazy future time (usually inside
UpdateDrawProperties).
