regarding libspdm_append_message_X

[zlyanz13]

When processing unit test for responder certificate,
function libspdm_append_message_b is called and buffer for hash context is allocated.
But after that, it does not free the buffer which leads to memory leak.
Do I have to reset the buffer manually?

So there is libspdm_reset_context but that just resets the context to be used again. Looks like we need a teardown function that would free any memory allocated by the cryptography library.
