bpo-44708: Only re-run test methods that match names of previously failing test methods (GH-27287)

Browse source 
* Move to a static argparse.Namespace subclass
* Roughly annotate runtest.py
* Refactor libregrtest to use lossless test result objects
* Only re-run test methods that match names of previously failing test methods
* Adopt tests to cover test method name matching
