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.

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.

Add getters to the ZNS specific data structures, so that an
SPDK application, e.g. examples/nvme/identify/identify.c,
has the ability to get and utilize the information in them.
