feat(feedback): Add "outline focus" and "foreground hover" vars (#9462)

* **BREAKING** `inputBorderFocus` is now `inputOutlineFocus` (I wanted
to make this directly tied to the css property being used to avoid
confusion)
* added `submitOutlineFocus`, `submitForegroundHover` (as well as the
`cancel` versions)
* change to use `:focus-visible` pseudo class (instead of `:focus`)
* do not show `buttonLabel` if empty

Closes #9439
