Fix and enable the PatternsDataSet_GenerateInputsWithNonBacktracking_MatchWithAllEngines test

[stephentoub]

#79364 added a new test that iterates through all of the patterns we have in our patterns database and for each:

• uses the NonBacktracking engine's SampleMatches function to generate inputs that match the pattern
• calls IsMatch with each of those inputs on a Regex created for that pattern/option with each of our engines

The test is still disabled, however, as there's a variety of work required to get it "production ready":

• SampleMatches ends up asserting on some patterns and hanging on others. This is likely one or more bugs in the SampleMatches implementation.
• The test takes a really long time to execute.
• It's only currently able to validate inputs expected to match. We also want to validate inputs expected to not match.
• It's possible for some patterns it could generate inputs that take too long to process. We'll want to explore using timeouts.
