Moves the uploading Attachments queue from the media workspace view to the uploader itself. This ensures that all attachments are added to the central attachmnet store.
Updates wp.Uploader to pass Attachment models to callbacks instead of Plupload file objects. Attachments in the process of uploading have a reference to the file object (which can be fetched by calling `attachment.get('file');`).
Also updates the customizer to be compatible with the API changes.

* This moves our "development" versions from .dev.js to .js (same for css).
* The compressed version then moves from .js to .min.js (same for css).
By switching to the standard .min convention, it sets expectations for developers,
and works nicely with existing tools such as ack.
fixes#21633.
