feat(app/device_assignment): add support for libspdm_get_certificate

In dev_assign_cmd_init_connection_main add support to do
libspdm_get_certificate. This retrivies device certificate in parts or
whole based on the size of device certificate and response buffer size.

As the device certificate is retrived, RMM does below steps
- Sets cache fields in DevCommExit for NS host to cache the device
  response.
- Computes spdm_cert_chain hash based on the negotiated hash algorithm.
- Computes x509_cert_chain hash based on the PDEV hash algorithm.
- Once the certificate is completed retrived, RMM sets the hash of the
  certificate in libspdm connection using custom set_data command
  LIBSPDM_DATA_PEER_USED_CERT_CHAIN_HASH.

Set LIBSPDM_MAX_CERT_CHAIN_SIZE to 0 as RMM do not store certificate
chain in libspdm context.
