Data grid/wrap complex filters

[vvval]

Allows wrapping standalone filters into a complex construction under the hood:
?filters[size]=xl&filters[color]=red
to mean

new Filter\Any(
    new Filter\Equals('size', 'xl'),
    new Filter\Equals('color', 'red')
)

A user should add a custom wrapper explicitly with the exact logic of wrapping:

$input = new ArrayInput([GridFactory::KEY_FILTER => ['size' => 'xl', 'color' => 'red', 'price' => 1]]);

$schema->addFilterWrapper(
    function (array $filters): array {
        $size = $filters['size'] ?? null;
        $color = $filters['color'] ?? null;
        if ($size && $color) {
            unset($filters['size'], $filters['color']);
            $filters[] = new Any($size, $color);
        }
        return $filters;
    }
);

This means that only if both size and color filters presented, group them with any and delete from the original list of filters
