Add a media from the media library failed - Access Denied 403

The media library performs a create_access check on the entity level, when selecting or creating a media.

If a user don't have the permission "create $bundle" then, the create_access check failed. The "administer nodes" permission isn't check by the create access method. And then we get this ajax error when selecting a media.

#3038254: Delegate media library access to the "thing" that opened the library

In the case of micro node, users of a micro site can create content, even if they don't have the global permission "create $bundle". So let's provide a create_access hook to handle this use case.

This fix should need probably to be moved on the micro_site module itself to handle create_access for all content entities once content entities will be supported out if the box by micro site.
