Customizer: Improve handling of crops in the media library.

This is a follow up on r41732, implementing the following improvements:

* Attachment parent info is now stored in attachment meta rather than a 
separate post meta key.
* Attachments created from contextual crops (e.g. header, logos, etc.) are
filtered out of the media library using a new `_filterContext` method in
`wp.media.controller.Library`.
