This PR adds whereInId to EntryRepository. See docs PR

$items = \Statamic\Facades\Entry::whereInId([ 3, 1, 0, 2 ]);

$this->assertInstanceOf(\Statamic\Entries\EntryCollection::class, $items);
$this->assertCount(3, $items);
$this->assertEveryItemIsInstanceOf(\Statamic\Contacts\Entries\Entry::class);
$this->assertEquals([ 3, 1, 2 ], $items->map->id());

Notable functionality:

• Entries are returned in order of their id's position in the original input argument.
• Missing IDs are omitted from resultant collection.
• Entries are first loaded from Blink, if cached, and remainder are loaded from the DB.

Relevancy to core

This is part of a wider piece of work I've start to add a fairly large reduction in DB queries to the statamic/eloquent-driver. The principal idea is to route as many components as possible through the repositories. As I was adding this to the package, parity with the core Repository contract felt good as well: PR on statamic/cms.

Note: original method was findByIds.
