### 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.
RID ip = openxr_api->interaction_profile_create(xr_interaction_profile->get_interaction_profile_path());
			if (ip.is_valid()) {
				openxr_api->interaction_profile_clear_bindings(ip);
				Array xr_bindings = xr_interaction_profile->get_bindings();
				for (int j = 0; j < xr_bindings.size(); j++) {
					Ref<OpenXRIPBinding> xr_binding = xr_bindings[j];
					Ref<OpenXRAction> xr_action = xr_binding->get_action();
					Action *action = nullptr;
					if (xr_actions.has(xr_action)) {
						action = xr_actions[xr_action];
					} else {
						print_line("Action ", xr_action->get_name(), " isn't part of an action set!");
						continue;
					}
					PackedStringArray paths = xr_binding->get_paths();
					for (int k = 0; k < paths.size(); k++) {
						openxr_api->interaction_profile_add_binding(ip, action->action_rid, paths[k]);
					}
				}
				
				openxr_api->interaction_profile_suggest_bindings(ip);
				
				if (interaction_profile_array.has(ip)) {
					interaction_profile_array.push_back(ip);
				}
			}
		}
	}
