[Router] Added Regression Tests for Parallel Connection Router
Added regression tests for parallel connection router by appending extra sets of configurations to those VTR flow regression tests previously selected by Fahri for testing coarse-grained parallel router. Removed VPR connection router test (vpr/test/test_connection_router.cpp), since it has been out-dated for a very long time and has caused lots of trouble for running VPR C++ tests locally.
