`gpu-probe` cross-compiled with cargo-ndk and run inside a default
`emu up`: the guest's GL adapter is the host's real RX 7900 XT through
virgl, reporting OpenGL ES 3.1 with compute shaders, 1024 invocations per
workgroup and 64 KB of workgroup storage -- the same numbers the desktop
gets. `Backends::PRIMARY` still finds nothing, because the guest's only
Vulkan is SwiftShader.
So GPU acceleration in the emulator is not a thing to get working; it is
the default, and it is GLES. What is missing is GPU-accelerated Vulkan,
and the Venus retry on mesa 26.2.2 fails exactly as it did on 26.1.7 with
no newer emulator package to try.
