XR: Add Vive Tracker interaction profile extension

Browse source 
This PR enables the OpenXR Vive Tracker interaction profile[1], so that
Vive Trackers can be accessed through the Blender Python API. It just
adds `XR_HTCX_VIVE_TRACKER_INTERACTION_EXTENSION_NAME` to the list of
tried-to-enable extensions. I grouped it after the other HTC interaction
profiles.

This allows add-ons to use Vive Trackers in their code, but requires no
further modifications to the C++ module. I will be using it in Tracking
Toolkit[2] for native Blender XR integration, but it opens up feature
possibilities for many projects that use the XR bpy PY API (eg. scene
inspector).
