transport: Introduce a transport for testing purposes
I've put the test transport header along side the source file as its
presence and implementation is an internal detail to support the test
suite. No consumers of libpldm outside its test suite should have any
need for the test transport. We can always choose to make the header
public if for some reason someone does eventually want to use it.
In addition, add a new test suite exercising the transport interfaces.
