Add gr_cb class to help tracking command buffer uses of GrGpuResources.
Essentially GrGpuResources have two counts now. The original fRefCnt has
not changed and is still used for things like knowing if we can reuse
a scratch texture. The new fCommandBufferUsageCnt is used to track
when a resource is in use on a command buffer or gpu in general. We now
delay calling notifyRefCntIsZero until both of the counts are zero.
