OpenXR SDK (Source) 1.0.25

OpenXR SDK 1.0.25 (2022-09-02)

This release contains a few specification clarifications and consistency
improvements, as well as some new vendor extensions. The OpenXR loader for
Android now supports API layers packaged in the application APK, which is
important for running the conformance tests, and which may also be used for
running with the validation layer enabled during application development, for
example. The loader design doc has been updated accordingly. The spec generation
toolchain scripts have been synchronized with Vulkan. Hello_XR now models the
recommended approach for selecting an environment blend mode, among other fixes.
