The MaxComputeWorkGroupInvocations constant is used in
compute_version_es2() instead of extensions->ARB_compute_shader
as ES has lower requirements than desktop GL.
Both i965 and gallium set this constant before enabling compute support.

This currently causes radeonsi to erroneously report GLES 3.1 support
as compute is the last missing part.
Even if the radeonsi compute patches land soon, they depend on a new
LLVM version (and for SI also new kernel), and this may affect other
drivers in the future.
Tested on radeonsi only.
I don't have commit access, so if this patch is acceptable someone else
will need to push it.
