Trashes or deletes an attachment.
When an attachment is permanently deleted, the file will also be removed. Deletion removes all post meta fields, taxonomy, comments, etc. associated with the attachment (except the main post).
The attachment is moved to the trash instead of permanently deleted unless trash for media is disabled, item is already in the trash, or $force_delete is true.
