Replace OnMemoryStateChange() with OnPurgeMemory() in RendererFrameManager

Replace OnMemoryStateChange() with OnPurgeMemory() in RendererFrameManager

We added OnPurgeMemory() callback to MemoryCoordinatorClient so that we
can separate memory purging from memory state transition (See [1] for
the motivation of this separation). This CL replaces OnMemoryStateChange()
with OnPurgeMemory() in RendererFrameManager because it just purges
memory.
