transport: storage: add support for SPDM over the storage binding (DSP0286) #2827

  1. library: Initial support for storage transport 

    As defined by DSP0826, add support for SPDM storage transport. The
transport layer uses a virtual storage header that encapsulates SPDM
requests to allow the caller to generate the required parameters
for a storage SPDM request. SPDM responses are not transport encoded,
with this header, instead just the message is returned.

  2. req_communication: pass session ID to transport 

    This allows transports such as Storage (DSP0286) to determine if the
next response is protected via secured messages. Unlike other transport
layers, storage does not encode the message type in a response header.
As such, the requester must track the expected type.

The issue [1] discusses this implementation requirement in further
detail with regards to DSP0286.
