Make order of port names determined in IR

[rkazants]

Root cause analysis: IR can be generated with undetermined order of output port names on different machines. It leads to failure during IR comparison check. Investigation showed that get_tensor_names can return port names in undetermined order due to use of set structure in one of auxiliary functions.

Solution: Make get_tensor_names generating port names in determined order (alphabetically sorted). We also considered
a way to fix IR comparator to be invariant to port names order but it requires more effort or even to switch off ports attribute check. We decided to stop on the first solution.
