Revert 189475 "cc:: Add RenderingStatsInstrumentation to manage ..."

semi-speculative revert for cc_unittests failures - see bug.

> cc:: Add RenderingStatsInstrumentation to manage collection of RenderingStats
> 
> This change adds the class RenderingStatsInstrumentation that manages conditional
> saving and thread-specific access to a private RenderingStats instance.
> An instance of RenderingStatsRecorder is created on LayerTreeHost, which
> passes references to LayerTreeHostImpl and TileManager. Access to reading
> and writing on the internal RenderingStats instance is guarded by a lock.
> 
> All rendering stats saving in LayerTreeHost, Single-/ThreadProxy,
> LayerTreeHostImpl and TileManager has been switched to use the
> RenderingStatsInstrumentation. Stats collection within Layer::update() still
> follows the original structure to keep this change small.
> 
> BUG=181319
> NOTRY=true
