XR: Update controller data again in viewer update

This is needed to draw the controllers with correct transforms in the
event that an operator changed the navigation.

XR: Add location/rotation locks for navigation

XR: Add grab navigation operator

Similar to the XR grab transform operator but applies deltas to the
navigation matrix instead of objects. Supports bimanual interaction
for viewer/navigation scaling and locks for rotation and scale.

XR: Smooth transition between modal actions

Although only one modal action is allowed at a time, if another
modal action is pressed when the current modal action ends, then
transition immediately to that one.

XR: Fixes/adjustments when viewer scale != 1.0

This corrects some clipping and shading issues when a scale factor
is applied to the XR viewmat. Also fixes the viewer pose calculation
with VR navigation.

Remove duplicate file

Was renamed to "wm_xr_action.c".

XR: Add bimanual scale mode for grab operator

Also renamed operator to "Transform Grab".

XR: Add axis region, bimanual action flags

The axis flags allow binding actions to certain regions of an input
axis (positive or negative). In this way, two different actions can
be bound to the input path "/input/thumbstick/x" without overlapping.

The bimanual flag signifies that the action depends on inputs from
both of its subaction paths, and both states, if available, will then
be passed to the operator. This will be used in the future for
two-handed navigation and transform.

XR: Add teleport navigation operator

Mostly the same as the XR raycast select operator. Users can
optionally constrain the result to specific axes, for example to
achieve "elevation snapping" behavior by constraining to the Z-axis.

Credit to KISKA for the elevation snapping concept.

XR: Add initial navigation support

Adds navigation transforms (pose, scale) to the XR session state
that will be applied to the viewer/controller poses.

Users can access these transforms via Python
(xr_session_state.navigation_location/rotation/scale) to use with
custom operators.
