godot/core/input_map.h
Nibodhika 1e28f63bcf Allows to map an action to all devices.
This is accomplished by setting a special value (-1) to the device variable
in the InputEvent that's being used to compare with the one received from the OS.

This special value is invalid for a regular input, so it should be safe.
Implements #17942
