Change how resizable images work (#1859)
* Add ResizableImage.svelte in ts/editable

* Set image constrained via attributes instead of managed style sheet

* Implement new constrained size method

* Turn WithImageConstrained.svelte into normal ts file

* Introduce removeStyleProperties

Removes "style" attribute if all style properties were cleared

* Avoid --editor-width and use one variable set on container

* Disable shrinking if already smaller than shrunken size

* Add button to restore image to original size

* Don't allow restoring original size if no custom width set

* Bottom-center HandleLabel

* Satisfy svelte-check
