description:
Prepare for new compat_netbsd32_mqueue module to be split out of
compat_netbsd32. Refactor the COMPAT_50 code related to mqueue,
and update the syscall definitions. Remove dependency on mqueue
from the compat_netbsd32 module (the new module will gain this
dependency).
Continuation of work on PR kern/50489
