gl_device: Filter more specifically for slow ASTC
Adds a check to find if the renderer is Intel DG (i.e. DG2). gl_device: Detect Mesa to disable their ASTC In our testing, our own ASTC decoder has shown itself to perform faster than the included one from the driver. Disable theirs when Mesa is detected. Mesa detection depends on the vendor string. Some drivers never appear outside of *nix contexts, so only check those in the *nix context. gl_device: Internalize Intel DG detection
