VK_FORMAT_{R8G8B8,B8G8R8}_{UNORM,SRGB} describe a 3-component, 8bpc,
24bpp, format. This is mapped to that type for Android, and implemented
as such by panvk. radv maps these to 4-component/32bpp formats, but only
support these formats for buffers rather than images. The outlier is
ANV, which relies on the 24->32bpp mapping to happen.
The Wayland WSI was mapping this to the 32bpp R8G8B8A8/B8G8R8A8 formats
instead. This would cause a failure to import the dmabuf into the
compositor on panvk, as it would send a buffer which was too small. (Or,
if it did import: garbage.)
