[Feature] Implement parameter widening feature for generated code (#380)

[lisachenko]

This PR introduces logic of skipping parameter types for children classes, according to the implemented in 7.2 parameter widening.

So, you can apply this feature to control manually parameter binding or conversion. This can be ParamConvertors, parameter injectors, etc..

To enable this feature, add into kernel initialization:

// Initialize demo aspect container
AspectKernel::getInstance()->init([
    // ... other config options
    'features' =>Features::PARAMETER_WIDENING,
]);

Please, remember, that this feature is available only for PHP>=7.2.0
