[Feature Request] Autofixer attachments over `bind:this`/`actions`

[paoloricciuti]

More often than not, when you use bind:this or an action, you should use an attachment. For bind:this, the suggestion should be more blunt, something like Check if you can use an attachment, if not, it's fine. For actions it should only trigger if the function used in the action is declared in the same component.
