This PR adds a toValuesCollection macro onto the Collection class.

Now you can do $collection->toValuesCollection() and it will convert it to a ValuesCollection filled with Values instances.

This is intended to be glue between the Blade wrapper introduced in #5201 and the query builder stuff in #5285.

Now you can perform a query in your Blade template, and convert it to a ValuesCollection so it's nice to loop over.

@foreach (Statamic::query('entries')->get()->toValuesCollection() as $entry)
  {{ $entry->title }}
  {{ $entry->toggle_field }}
@endforeach
