### Godot version

4.2.dev 80de898d721f952dac0b102d48bb73d6b02ee1e8

### System information

OpenXR

### Issue description

The Godot 3 OpenXR plugin supported obtaining boundary/guardian information in order to obtain play space logic. While we do have a function in the `XRInterface` in Godot 4 that is supposed to retrieve this information (`get_play_area`) it is not implemented on the Godot 4 `OpenXRInterface`.

This logic needs to be ported.

### Steps to reproduce

Call `get_play_area`, be amazed by it not returning data :P

### Minimal reproduction project

Any XR project.
if (p_session == XR_NULL_HANDLE) {
		p_session = session;
	}
	Tracker *tracker = tracker_owner.get_or_null(p_tracker);
	ERR_FAIL_NULL(tracker);
	if (tracker->toplevel_path == XR_NULL_PATH) {
		
		return;
	}
	XrInteractionProfileState profile_state = {
		XR_TYPE_INTERACTION_PROFILE_STATE, 
		nullptr, 
		XR_NULL_PATH 
	};
	XrResult result = xrGetCurrentInteractionProfile(p_session, tracker->toplevel_path, &profile_state);
	if (XR_FAILED(result)) {
		print_line("OpenXR: Failed to get interaction profile for", itos(tracker->toplevel_path), "[", get_error_string(result), "]");
		return;
	}
	XrPath new_profile = profile_state.interactionProfile;
	XrPath was_profile = get_interaction_profile_path(tracker->active_profile_rid);
	if (was_profile != new_profile) {
		tracker->active_profile_rid = get_interaction_profile_rid(new_profile);
		if (xr_interface) {
			xr_interface->tracker_profile_changed(p_tracker, tracker->active_profile_rid);
		}
	}
