### 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.
XrResult result = xrSuggestInteractionProfileBindings(instance, &suggested_bindings);
	if (result == XR_ERROR_PATH_UNSUPPORTED) {
		
		print_verbose("OpenXR Interaction profile " + ip->name + " is not supported on this runtime");
	} else if (XR_FAILED(result)) {
		print_line("OpenXR: failed to suggest bindings for ", ip->name, "! [", get_error_string(result), "]");
		
	}
	/* For debugging:
	print_verbose("Suggested bindings for " + ip->name);
	for (int i = 0; i < ip->bindings.size(); i++) {
		uint32_t strlen;
		char path[XR_MAX_PATH_LENGTH];
		String action_name = action_get_name(get_action_rid(ip->bindings[i].action));
		XrResult result = xrPathToString(instance, ip->bindings[i].binding, XR_MAX_PATH_LENGTH, &strlen, path);
		if (XR_FAILED(result)) {
			print_line("OpenXR: failed to retrieve bindings for ", action_name, "! [", get_error_string(result), "]");
		}
		print_verbose(" - " + action_name + " => " + String(path));
	}
