Turns out we did have a hook for this already! But it is used to draw or not inner button styles, so not quite equivalent. I had to expand the amount of things it applies to because buttons and such do paint focus indicators in all widgets. This patch could cause some undesired outlines in some widgets. I hope not (I tried to audit to the best of my knowledge), but in that case they'd be just more values to add to the list. Differential Revision: https://phabricator.services.mozilla.com/D74733
