Add TWRP app install via TWRP recovery

Browse Source 
Note: I will have to add a build flag for excluding the app later for
watches and maybe Android TV. I will also have to add support in the
tablet and watch layouts later. I will merge this for the initial roll out
to select devices and finish up later.
