Batch noteOperation binder calls in the client to reduce call volume

The binder API AppOpsService#noteOperation has significant high call volume. One of the reasons is the clients are often making burst calls like 2k ~ 3k/second. This CL adds a buffer on the client side that aggregates same noteOp calls within a second and sends aggregated count asynchrnously to the system service. On the client side, it also uses op mode cache introduced in ag/29819090 to return op mode.

Note: This CL doesn't change current contract of onNotedOp callback. Client will still receive a callback for every noteOp call, including self, sync, async callback. To reduce the async callback spam, there is another flag that controls whether we can reduce the number of callbacks to 1.
