Mark Paluch ed34f2aef8 Add negative-caching in PreferredConstructor.isConstructorParameter(…). ...

We now cache the negative outcome of PreferredConstructor.isConstructorParameter(…) to avoid iterations and iterator allocations which roughly improves typical converter usage by roughly 32%.

Before:
Benchmark                                                               Mode  Cnt        Score        Error  Units
TypicalEntityReaderBenchmark.simpleEntityGeneratedConstructorAndField  thrpt   10  6848447,474 ± 554354,377  ops/s

After
Benchmark                                                               Mode  Cnt        Score         Error  Units
TypicalEntityReaderBenchmark.simpleEntityGeneratedConstructorAndField  thrpt   10  9071099,879 ± 1423166,087  ops/s

Closes #2295.
