Fix InvalidOperationException in AbstractRemoveUnusedParametersAndValuesDiagnosticAnalyzer.ShouldReportUnusedParameters

We recently changed the enum values for `UnusedParametersPreference` (see https://github.com/dotnet/roslyn/commit/ee61cc53ff02b55df8c9d756235c0e1085dafa4b), which seems to lead to this exception if customers had explicitly changed this option in the Tools Option page prior to that fix. I have changed the code to be much more defensive.

Fixes #37326
