### 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_action.is_null()) {
		return String("None");
	}
	Action *action = action_owner.get_or_null(p_action);
	ERR_FAIL_NULL_V(action, String());
	return action->name;
}
void OpenXRAPI::action_free(RID p_action) {
	Action *action = action_owner.get_or_null(p_action);
	ERR_FAIL_NULL(action);
	if (action->handle != XR_NULL_HANDLE) {
		xrDestroyAction(action->handle);
	}
	action_owner.free(p_action);
}
RID OpenXRAPI::get_interaction_profile_rid(XrPath p_path) {
	List<RID> current;
	interaction_profile_owner.get_owned_list(&current);
	for (int i = 0; i < current.size(); i++) {
		InteractionProfile *ip = interaction_profile_owner.get_or_null(current[i]);
		if (ip && ip->path == p_path) {
			return current[i];
		}
	}
	return RID();
