Give an option to choose default display_id

Problem/Motivation

Currently there are 2 display modes available - Grid and Table.
It would be great if there is an option which one would be the default one when to edit Media field.

Expected Steps

1. Create and configure new Media field on specific node.
2. Go to Manage form display page for the node.
3. If choose Media library widget, there will be configuration available to choose default display_id, so that when to edit node, and click "Add Media" button, specific block will be rendered as default.

Proposed resolution
