Introduce --keyboard and --mouse

Until now, there was two modes for keyboard and mouse:
 - event injection using the Android system API (default)
 - HID/AOA over USB

For this reason, the options were exposed as simple flags:
 - -K or --hid-keyboard to enable physical keyboard simulation (AOA)
 - -M or --hid-mouse to enable physical mouse simulation (AOA)

Replace them by explicit --keyboard and --mouse options, with 3 possible
values:
 - disabled
 - sdk (default)
 - aoa

This will allow to add a new mode (uhid).
