### 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_interaction_profile.is_null()) {
		return String("None");
	}
	InteractionProfile *ip = interaction_profile_owner.get_or_null(p_interaction_profile);
	ERR_FAIL_NULL_V(ip, String());
	return ip->name;
}
void OpenXRAPI::interaction_profile_clear_bindings(RID p_interaction_profile) {
	InteractionProfile *ip = interaction_profile_owner.get_or_null(p_interaction_profile);
	ERR_FAIL_NULL(ip);
	ip->bindings.clear();
}
