[CssSelector] Support has CSS selector

[janopae]

Description

The has CSS selecter selects the parent of an element that complies to a certain CSS selector. This would be incredibly useful for tests.

https://developer.mozilla.org/en-US/docs/Web/CSS/:has

Example

$tableRowContainingEntity = $table->filter("tr:has(td:contains(\"{$entity->geTitle()}\"))");
self::assertNotEmpty($tableRowContainingEntity);

$secondCell = $tableRowContainingEntity->filter(':nth-child(1)');
self::assertEquals($entity->getDescription(), $secondCell->text());

@xabbuh Thanks for pointing this out! I didn't find it.

For the mean time (until it's merged): I just realised that the Crawler allows you to get a node's parent with ->ancestors()->first(). So at least for the case that I provided as an example, it is a workaround to select the child with the CSS selector and then get the parent with the craweler.
