base: Long press power button to toggle flashlight [1/2]

 * Thanks to beanstown106 for the initial longpress action calls in
   PhoneWindowManager (improved by lineage guys)

 * Remove the settings pref if the device doesn't have flashlight

 * Vibrate when toggling torch to let the user know of unwanted toggling
   in the pocket (even if vibration is disabled by user)

 * Allow torch action also on ambient display

[AEX Edits] :
- Port to S
- simplify code

[mydongistiny]:
- Fixed for android10

[DennySPB] :
- base: ScreenOff torch: Allow to disable torch when screen is on

[mickaelmendes50] :
- Adapt to AOSPA

 * We don't allow users to use the Double Press power option,
   so remove the non used code.
 * Removed "double press power to toggle torch"
 * Removed "handle camera gesture here instead of extensions"
 * Removed "Add 170ms delay for double tap action"
