GPA 3.0 Preview Update 1

This is a minor update to the GPA 3.0 preview release. It fixes a few issues with device detection in the OpenGL path, as well as an issue with locating the Vulkan library on Linux. It also updates the set of suppored devices to include more recent GPUs/APUs.

This is being provided for integration into RenderDoc 1.0 (current RenderDoc 1.x nightly builds have GPUPerfAPI integration)
