spdm: add spdm storage transport virtual header

Browse source 
This header contains the transport encoding for an SPDM message that
uses the SPDM over Storage transport as defined by the DMTF DSP0286.

Note that in the StorageSpdmTransportHeader structure, security_protocol
field is defined in the SCSI Primary Commands 5 (SPC-5) specification.
The NVMe specification also refers to the SPC-5 for this definition.
The security_protocol_specific field is defined in DSP0286 and is
referred to as SP Specific for NVMe and ATA.
