RFR: 8330755: ProblemList files have entries referring to non-existent tests

[Doug Simon]

This PR adds a check for the format of ProblemList files and ensures they only have entries referring to existing tests.

The cleanups in the second commit of this PR were done based on the output of `CheckProblemLists`:
