ANDROID: vendor_hooks: Add vendor hooks for key combination 



When some problems happened in android, we can't use adb command because
android can be abnormal state. And we can't use uart because
uart pin is not connected in the board. So we need key combination
functions for debugging.
This function should only use in development environment.
In the market, this will be disabled.
