Early return Collectors when narrow-param is disabled

[staabm]

collectors store their data in the PHPStan result cache. we shouldn't pollute the result cache with data if we don't need it.

looking at the sources it seems these 3 collectors are only used for NarrowPublicClassMethodParamTypeRule and this rule has a configuration flag to early return if not enabled.

with this PR we now use the same configuration flag to early return in the related collectors

this PR came together because it turned out that one of the type-perfect collectors was by-far the most result-cache polluting component in our project:

mstaab@NB-COMPLEX-61 MINGW64 ~/AppData/Local/Temp/phpstan
$ grep 'collectorType' resultCache.php  > collectors.txt

mstaab@NB-COMPLEX-61 MINGW64 ~/AppData/Local/Temp/phpstan
$ sort collectors.txt | uniq -c
    283        'collectorType' => 'PHPStan\\Rules\\DeadCode\\ConstructorWithoutImpurePointsCollector',
      1        'collectorType' => 'PHPStan\\Rules\\DeadCode\\FunctionWithoutImpurePointsCollector',
    558        'collectorType' => 'PHPStan\\Rules\\DeadCode\\MethodWithoutImpurePointsCollector',
    351        'collectorType' => 'PHPStan\\Rules\\DeadCode\\PossiblyPureFuncCallCollector',
    391        'collectorType' => 'PHPStan\\Rules\\DeadCode\\PossiblyPureMethodCallCollector',
    133        'collectorType' => 'PHPStan\\Rules\\DeadCode\\PossiblyPureStaticCallCollector',
      3        'collectorType' => 'PHPStan\\Rules\\Traits\\TraitDeclarationCollector',
     34        'collectorType' => 'PHPStan\\Rules\\Traits\\TraitUseCollector',
    947        'collectorType' => 'Rector\\TypePerfect\\Collector\\ClassMethod\\PublicClassMethodParamTypesCollector',
   4765        'collectorType' => 'Rector\\TypePerfect\\Collector\\MethodCall\\MethodCallArgTypesCollector',

after his PR the result-cache of said project shrunk by ~16% in file-size - because we don't use narrow_param in our projects - which in turn makes phpstan analysis faster and less memory hungry

Makes sense 👍
