hw/nvme: Add NVMe NGUID property
This patch adds a way to specify an NGUID for a given NVMe Namespace using a
string of hexadecimal digits with an optional '-' separator to group bytes. For
instance:
-device nvme-ns,nguid="e9accd3b83904e13167cf0593437f57d"
If provided, the NGUID will be part of the Namespace Identification Descriptor
list and the Identify Namespace data.
