feat(ophints): add goggles for non-evil users

[Dev380]

This adds the goggles package as a module flag
to use goggles instead of volatile-highlights-mode as a non-evil user.

Is there any compelling reason to keep volatile-highlights? If not, I'd rather do away with it entirely.

[Dev380]

I'm not sure how the release schedule works so I kept it in to avoid a breaking change; should vhl be removed and goggles.el be the new default when evil is off?

VHL is removed
