test: Fix test failures after master merge

Update test code to match API changes from upstream master:

- TestGraph.cc: Fix makeScenes() call to pass reference instead of pointer
- TestLibertyClasses.cc: Fix ScaleFactorType wire_res/wire_cap name mapping;
  fix TablePtr usage by calling .get() where const TableModel* is expected
- TestLibertyClasses.cc: Update liberty_read_nangate.ok for new timing arc output
- TestPower.cc: Replace PwrActivityOrigin::defaulted with ::unknown;
  fix isSet() expectations (unknown origin returns false)
- TestSdcClasses.cc, TestSdf.cc, TestUtil.cc, TestSpice.cc:
  Fix RiseFall::to_string() expected values from short form ("^"/"v")
  to long form ("rise"/"fall")
- TestUtil.cc: Remove tests for deleted StringVector/split/TokenParser
  and StringSet::deleteContents (removed from master)
- TestSpice.cc: Replace StdStringSeq with StringSeq
- helpers.tcl: Use pwd-based result_dir so module tests write results
  to their own test/results/ directory
- verilog_bus.ok: Update golden file for new port ordering from master
