Expose the config and display for EGL-based QOpenGLContexts
...in the native interface.
Using OpenXR is impossible on some platforms (for example, Android)
without knowing all three. The EGLContext alone is not enough, and
EGL offers no way to query the EGLConfig a context was created with.
https://www.khronos.org/registry/OpenXR/specs/1.0/html/xrspec.html#XR_KHR_opengl_es_enable
Therefore, expose all three so libs/apps can use the new way to query
these native resource without resorting to the old-style
nativeResourceFor* queries.
