The CTS tests always use random image sizes for testing images, which was not valid for PVRTC1 textures. With 1.3.279 a VUID was added to require power-of-two dimensions for PVRTC1 textures, as discussed in KhronosGroup/Vulkan-Docs#1991.
Also, this fixes a bug introduced with 4c7e4e9, as it required the extension to be present for the PVRTC formats to be tested, but it was never added as a extension to be enabled, so PVRTC textures were never tested.
