move integrity settings to queue_limits

Hi Jens, hi Martin,

this series converts the blk-integrity settings to sit in the queue
limits and be updated through the atomic queue limits API.

I've mostly tested this with nvme, scsi is only covered by simple
scsi_debug based tests.

For MD I found an pre-existing error handling bug when combining PI
capable devices with not PI capable devices.  The fix was posted here
(and is included in the git branch below):

   https://lore.kernel.org/linux-raid/20240604172607.3185916-1-hch@xxxxxx/

For dm-integrity my testing showed that even the baseline fails to create
the luks-based dm-crypto with dm-integrity backing for the authentication
data.  As the failure is non-fatal I've not addressed it here.

Note that the support for native metadata in dm-crypt by Mikulas will
need a rebase on top of this, but as it already requires another
block layer patch and the changes in this series will simplify it a bit
I hope that is ok.

The series is based on top of my previously sent "convert the SCSI ULDs
to the atomic queue limits API v2" API.
