XR: Check for valid stage reference space bounds

Even if the stage reference space is supported by the XR runtime, the
bounds may be invalid (0, 0) if the user did not define a tracking
space via the runtime's UI. In this case, fall back to the local
tracking space.

XR: Fix projection selection in edit mode

Use window region dimensions instead of XR surface dimensions. Add
winrct offset for box select.

XR: Fix raycast deselect empty for edit mode

XR: Use stage ref space for absolute tracking

XR: Add axis property to raycast select operator

Allows users to adjust the raycast axis to fit different poses and
controllers.

XR: Add "absolute tracking" session setting

Enables users to define the tracking origin in a way that is not
linked to the headset position. Instead, the tracking values given by
the XR runtime are left unadjusted and a user can manually calibrate
an "origin" landmark object to adjust to their real world space.

Can be useful for applications that use external tracking systems
and those that primarily only need to use controllers (e.g. for
motion capture).

XR: Ensure valid region for invoking operators

Check for a valid v3d, even if the area / region uses a viewport.

XR: Use TransInfo viewmat for transform modal_3d

Fixes static variable TODO.

XR: Compare absolute input value with threshold

Trackpad / thumbstick input values range from -1 to 1, so the
absolute value must be compared against the input threshold.

Fix build warnings on Linux / gcc

XR: Implement XR constraints toggle operator

Useful for quickly playing back recorded animations without
overwriting existing data.

XR: Support auto keying XR constraint objects

If specified, headset / controller objects will auto key on animation
playback. This can be useful for virtual camera applications.

XR: Fix crash when reading "constraint" objects
