Description Wenson Hsieh 2021-10-06 10:21:27 PDT 
Make it possible to avoid sending the wakeup message in StreamClientConnection, until some configurable number of messages have been queued up. This allows us to avoid triggering excessive wakeups in the GPU Process when using streaming IPC for display lists in the Canvas Lines subtest in MotionMark, which exercises sending a massive, constant stream of cheap drawing commands to the GPUP.
