Emulate zoned btrfs mode on non-zoned devices. This is done by "slicing
up" the block-device into static sized chunks and fake a conventional zone
on each of them. The emulated zone size is determined from the size of
device extent.

This is mainly aimed at testing parts of the zoned mode, i.e. the zoned
chunk allocator, on regular block devices.
