[4.3] XRNode - fix visibility issue

[BastiaanOlij]

This is an extract of a fix from #95153 for Godot 4.3

[dsnopek]

There's two other little changes from #95153, that I'm not sure if we need here as well.

In openxr_hand_tracking_extension.cpp:

• The godot_tracker->invalidate_pose("default"); added here, and
• Moving godot_tracker->set_has_tracking_data(true); from here to here

I think those both could potentially have an effect on whether or not the node thinks it has data or not, in a couple of edge cases.

Thanks @dsnopek ,

Made the changes you suggested, indeed will help. I also fixed the issue with the wrong bit being checked.

Looks great to me!

I just tested on Quest 3, and the visibility checks seem to be working correctly.
