Touchscreen: Allow mods to swap the meaning of short and long taps (punch with single tap) (#14087)

Browse source 
This works through a new field "touch_interaction" in item definitions.
The two most important use cases are:
 - Punching players/entities with short tap instead of long tap (enabled by default)
 - Making items usable that require holding the place button (e.g. bows and shields in MC-like games)
