23a1916935 nvme: add function to get the max zone append data transfer size
The zone append command, which is part of the Zoned Namespace Command Set,
has a maximum data transfer size that can be less than or equal to mdts.

Since zone append commands will not be allowed to be split, the user has
to be able to get the maximum zone append data transfer size. Add a
function that returns this limit.

be3ff9c0b5 nvme: add function to get ZNS num zones
Add a function to get the number of zones for a zoned namespace.

Since the ZNS specification does not allow zone size == 0,
divide by zero should not be possible on a spec compliant drive.

3be2935701 nvme: move ZNS specific functions to their own header file
Move ZNS specific functions to their own header file:
include/spdk/nvme_zns.h.
This is similar to how it's done for e.g. NVMe-oF with
include/spdk/nvmf.h.

This avoids cluttering the nvme.h header with ZNS specific functions.

A SPDK program that wants to use the spdk_nvme_zns_* functions will
need to include include/spdk/nvme_zns.h, however, this is similar
to how e.g. spdk_nvmf namespaced functions work.
This change is safe to do now, since there is no SPDK release with
ZNS so far.
