In btrfs there's a few ways we limit the RAID profiles we'll use. We
have the raid56 feature that can be compiled out, zoned devices don't
support certain raid configurations, and you can manually set
BTRFS_PROFILE_CONFIGS to limit what you're testing.
To handle all of these different scenarios in the same way, update
_btrfs_get_profile_configs() to check for RAID56 support and remove it
if it is not there, and then add _require_btrfs_raid_type and
_check_btrfs_raid_type to get all the settings and then check if the
requested raid type is available.
From there I've updated all of the existing tests that use
_require_btrfs_fs_feature raid56
to use
_require_btrfs_raid_type <type>
where appropriate.

We also call notrun for zoned devices.
I suggest tweaking the notrun message to:
_notrun "$1 isn't supported by the profile config or scratch device"
I have made this change and applied it.
