OpenXR SDK (Source) 1.1.54

OpenXR SDK 1.1.54 (2025-12-02)

This release updates the C++ standards version used by the package, and includes
changes to hello_xr to bring it closer in line with the OpenXR-CTS (which come
from a shared codebase) and allow optional submission of depth textures where
supported, among other changes.
