[DX] make all configure() methods accept direct value object configuration

[TomasVotruba]

Follow up to #1285 and #1276

This enables much simpler configuration on classes using single value to input:

Before

    $services->set(AddReturnTypeDeclarationRector::class)
        ->call('configure', [[
            AddReturnTypeDeclarationRector::METHOD_RETURN_TYPES => ValueObjectInliner::inline([
                new AddReturnTypeDeclaration(PHPUnitTestCase::class, 'tearDown', new VoidType()),
            ]),
        ]]);

Now

    $services->set(AddReturnTypeDeclarationRector::class)
        ->configure([
            new AddReturnTypeDeclaration(PHPUnitTestCase::class, 'tearDown', new VoidType())
        ]);
