  1. feat(InputActionProperty): add functionality based around InputActions

    The InputActionProperty of the Unity Input System allows for listening
    to Input System Action events directly based off an input system action
    reference or from a direct binding.
    
    This is cleaner and easier to understand than the CallbackContext with
    Unity Events so it has been used to create some new prefabs in the
    samples directory.
    
    The new InputActionPropertyVelocityTracker will track velocity of an
    input system action which can be based off OpenXR device data, meaning
    the velocity reported should be compatible with the specific device
    rather than trying to use estimations.
    
    The new InputActionPropertyTransformer can also be used in place of the
    CallbackContextTransformer to provide a direct reference to an Input
    Action (or direct binding) which can be used to pick up action input
    directly within the component rather than having to go through the
    PlayerInput script and pass the context via a Unity Event to the
    CallbackContextTransformer.
    
    The InputActions_GenericXR.inputactions mapping has also been updated
    to include pose data for the HMD, controllers and pointer, which
    includes position, rotation and velocity information.
    
    This has all formalised in the creation of two new prefabs:
    
    * UnityInputSystem.Poses.GenericXR.prefab - contains tracked poses for
    the new pose data.
    * UnityInputSystem.InputActionMappings.GenericXR.prefab - contains all
    of the input buttons, axis data, etc for the generic controllers using
    the new InputActionPropertyTransformer, which makes it easier to see
    how to customise the system.
    
    This has also meant the UnityInputSystem.Mappings.GenericXR.prefab has
    been renamed to
    UnityInputSystem.CallbackContextMappings.GenericXR.prefab and this
    should not technically be considered as deprecated as it may still be
    useful or even the preferred usage, but by default the new
    InputActionMappings.GenericXR.prefab should be used.
