spdm-socket: add seperate send/recv functions

Browse source 
This is to support uni-directional transports such as SPDM over Storage.
As specified by the DMTF DSP0286.

Also update spdm_socket_rsp() to use the new send()/receive() functions. For
the case of spdm_socket_receive(), this allows us to do error checking
in one place with the addition of spdm_socket_command_valid().
