OpenXR SDK 1.0.28 (2023-07-10)

NOTE: Binary artifacts for Windows attached to this release correspond to the hotfix release release-1.0.28.1 tag, and binary artifacts for Android correspond to the hotfix release release-1.0.28.2 tag (the 1.0.28 artifacts have been removed as they were defective). See below for the contents of these SDK hotfix releases.

This release contains improved compatibility and code quality fixes for the
loader, support for loading certain API layers on Android-based devices, and a
number of other improvements, in addition to the new extensions. Additionally,
the loader documentation now describes how OpenXR handles compatibility with
Android API levels of 30 and above: runtimes may need to update accordingly to
support this compatibility solution.
