This reverts #110582 - the workaround is no longer needed, as MS have updated
the version of mesa they ship as part of their compatibility pack, which contains
a workaround on that side instead.
This means that the supported version of OpenGL based on the host GPU is now
correct, bar `GL_ARB_texture_view`.
`GL_ARB_texture_view` is faked for ARM64 devices, as the part that is not
implemented (channel casting) is not used in blender.
This means that ARM64 devices (at least) now report compatibility up to OpenGL
4.6 in the system info export.
