hwc/qservice: Add support for toggling bwc over binder

Browse Source 
Remove support for toggling BWC via property and add support to
toggle BWC over binder. This will take effect only on targets where
the driver enables BWC.

Example to disable BWC:
    adb shell service call display.qservice 17 i32 0
Where 17 is the code to toggle BWC, 0 to disable.
