OpenZFS on Linux and FreeBSD

Mateusz Piotrowski 576d34cb11 Turn default_bs and default_ibs into ZFS_MODULE_PARAMs
The default_bs and default_ibs tunables control the default block size
and indirect block size.

So far, default_bs and default_ibs were tunable only on FreeBSD, e.g.,

    sysctl vfs.zfs.default_ibs

Remove the FreeBSD-specific sysctl code and expose default_bs and
default_ibs as tunables on both Linux and FreeBSD using
ZFS_MODULE_PARAM.

One of the use cases for changing the values of those tunables is to
lower the indirect block size, which may improve performance of large
directories (as discussed during the OpenZFS Leadership Meeting
on 2022-08-16).
