### 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.
print_verbose(String("OpenXR resetting invalid display period ") + rtos(frame_state.predictedDisplayPeriod));
		frame_state.predictedDisplayPeriod = 0;
	}
	for (OpenXRExtensionWrapper *wrapper : registered_extension_wrappers) {
		wrapper->on_pre_render();
	}
	
	
	
	
	
	
	
	
	XrViewLocateInfo view_locate_info = {
		XR_TYPE_VIEW_LOCATE_INFO, 
		nullptr, 
		view_configuration, 
		frame_state.predictedDisplayTime, 
		play_space 
	};
	XrViewState view_state = {
		XR_TYPE_VIEW_STATE, 
		nullptr, 
		0 
	};
	uint32_t view_count_output;
	result = xrLocateViews(session, &view_locate_info, &view_state, view_count, &view_count_output, views);
	if (XR_FAILED(result)) {
