Subject: Fix Keyboard Input Hangs when using modifiers

Main input parsing loop only update actions for keyboard if the state has changed.
`InputMap::event_is_action` now ignores keyboard modifiers if the event is not pressed.
Clarify difference between `InputMap::action_has_event` and `InputMap::event_is_action` in docs.

Fixes #6388.
