cpuset: increase userland maximum size to 1024

Browse Source 
Hardware with more than 256 CPU cores is now available and will become
increasingly common.  Bump CPU_MAXSIZE (used for userland cpuset_t
sizing) to 1024 to define the ABI for FreeBSD 14.

This change is reapplied after a change to decouple cpuset from bhyve:
commit e17eca3276 ("vmm: Avoid embedding cpuset_t ioctl ABIs").
