anv: Don't advertise unsupported shader stages
We don't currently support mesh or ray tracing, so don't advertise their shader stages as supported for subgroups.
Due to an influx of spam, we have had to impose restrictions on new accounts. Please see this wiki page for instructions on how to get full permissions. Sorry for the inconvenience.
