hw/block/nvme: add metadata support
Add support for metadata in the form of extended logical blocks as well
as a separate buffer of data. The new `ms` nvme-ns device parameter
specifies the size of metadata per logical block in bytes. The `mset`
nvme-ns device parameter controls whether metadata is transfered as part
of an extended lba (set to '1') or in a separate buffer (set to '0',
the default).
Regardsless of the scheme chosen with `mset`, metadata is stored at the
end of the namespace backing block device. This requires the user
provided PRP/SGLs to be walked and "split" into data and metadata
scatter/gather lists if the extended logical block scheme is used, but
has the advantage of not breaking the deallocated blocks support.
