Create key inputs as physical by default in the input action editor

Physical Key should be used for most game inputs as it allows
keys to work on non-QWERTY layouts out of the box.
This is especially important for WASD movement layouts.

In contrast, remapped (non-physical) keys are mainly useful in
non-game applications, where shortcuts are expected to match a
precise letter rather than a location on the keyboard.
