Camera: Cache and defer Surface binder IPC calls
Try to cache and defer Surface related IPC configuration
calls. Specifically:
1) Avoid retrieving the consumer name until dump
2) Cache and re-use the surface consumer usage value
3) Configure the producer max undequeued buffer count
instead of the total buffer count
Additionally, raise the stream configuration thread
prioirty during the binder IPC intensive stream/surface
setup.

Test: Manual using camera application,
adb shell dumpsys media.camera
