block/block-backend: add block layer APIs resembling Linux ZonedBlockDevice ioctls
Add zoned device option to host_device BlockDriver. It will be presented only for zoned host block devices. By adding zone management operations to the host_block_device BlockDriver, users can use the new block layer APIs including Report Zone and four zone management operations (open, close, finish, reset, reset_all).
Qemu-io uses the new APIs to perform zoned storage commands of the device: zone_report(zrp), zone_open(zo), zone_close(zc), zone_reset(zrs), zone_finish(zf).
For example, to test zone_report, use following command: $ ./build/qemu-io --image-opts -n driver=host_device, filename=/dev/nullb0 -c "zrp offset nr_zones"

block: move has_variable_length to BlockLimits
At the protocol level, has_variable_length only needs to be true in the very special case of host CD-ROM drives, so that they do not need an explicit monitor command to read the new size when a disc is loaded in the tray.
However, at the format level has_variable_length has to be true for all raw blockdevs and for all filters, even though in practice the length depends on the underlying file and thus will not change except in the case of host CD-ROM drives.
As a first step towards computing an accurate value of has_variable_length, add the value into the BlockLimits structure and initialize the field from the BlockDriver.
