[DX] Add configure() method to service configuration to make configuration easy again

[TomasVotruba]

We're using Symfony PHP fluent configuration to add autocomplete and ECS, PHPStan and Rector luxury to configs.

Yet it comes for a price, of complex configuration, mainly in case of value objects. Symfony container cannot work with value objects natively, so extra inlining complexity has to be added:

Also it's prone to errors:

    ->call('configure', [[
    ->call('configure', [[[
    ->call('configure', [
    ->call('configure',

                TestCase::class => ValueObjectInliner::inline(PreferenceSelfThis::PREFER_THIS()),
         ],

        PreferThisOrSelfMethodCallRector::TYPE_TO_PREFERENCE => ValueObjectInliner::inline([
                TestCase::class => PreferenceSelfThis::PREFER_THIS(),
         ]),

        PreferThisOrSelfMethodCallRector::TYPE_TO_PREFERENCE => [
                TestCase::class => PreferenceSelfThis::PREFER_THIS(),
         ],

This bothers the user with boring knowledge. 👎

New ->configure(...) method 🎉

Instead, this PR gets the simplicity back. Rector DI itself handles the value object wrapping by adding special ->configure() method.

Before 🤧

$services->set(SomeChangeRector::class)
    ->call('configure', [[
        SomeChangeRector::SOME_CONFIG => ValueObjectInliner::inline([
            new SomeChange('before', 'after');
        ]),
    ]]);

Now 👍

$services->set(SomeChangeRector::class)
    ->configure([
        SomeChangeRector::SOME_CONFIG => [
            new SomeChange('before', 'after');
        ],
    ]);

public function configure(array $configuration): self
{
	// ...
}

With array parameter type hint useful for PHPStorm and PHPStan as a bonus ✔️

The config in config directory need to be updated ? eg:

rector-src/config/set/safe07.php

Line 12 in 511d649

->call('configure', [[

@samsonasik Yes, you're right.
This PR is a prototype testing, so I've updated only the rector.php. Maybe we missed something or there is a better way.

If it prooves to be right way, we can update all configs 👍
