move features flags into queue_limits v2

[Christoph Hellwig <hch@lst.de>]

Hi all,

this is the third and last major series to convert settings to
queue_limits for this merge window.  After a bunch of prep patches to
get various drivers in shape, it moves all the queue_flags that specify
driver controlled features into the queue limits so that they can be
set atomically and are separated from the blk-mq internal flags.

Note that I've only Cc'ed the maintainers for drivers with non-mechanical
changes as the Cc list is already huge.

This series sits on top of the for-6.11/block-limits branch.

A git tree is available here:

Changes since v1:
 - fix an inverted condition
 - fix the runtime flush disable in xen-blkfront
 - remove sd_is_zoned entirely
 - use SECTOR_SIZE in a few more places
 - fix REQ_NOWAIT disabling for dm targets that don't support it
 - fix typos
 - reword various commit logs
