Rob Norris f245541e24 zfs_file: implement zfs_file_deallocate for FreeBSD 14
FreeBSD 14 gained a `VOP_DEALLOCATE` VFS operation and a `fspacectl`
syscall to use it. At minimum, these zero the given region, and if the
underlying filesystem supports it, can make the region sparse. We can
use this to get TRIM-like behaviour for file vdevs.
