hw/block/nvme: end-to-end data protection
Add support for namespaces formatted with protection information. The
type of end-to-end data protection (i.e. Type 1, Type 2 or Type 3) is
selected with the `pi` nvme-ns device parameter. If the number of
metadata bytes is larger than 8, the `pil` nvme-ns device parameter may
be used to control the location of the 8-byte DIF tuple. The default
`pil` value of '0', causes the DIF tuple to be transferred as the last
8 bytes of the metadata. Set to 1 to store this in the first eight bytes
instead.
