refactor!(ophints): replace volatile-highlights w/ goggles

BREAKING CHANGE: This replaces volatile-highlights.el with goggles.el,
since the former is no longer maintained and the latter is a much
simpler implementation for the same functionality. No adjustments are
needed for end-users to adopt this change, unless they have
volatile-highlights-specific configuration.
