Joey Perrott d3b5e5696f style(dev-infra): enforce format on newly included files ()
Historically files to be formatted were added to a listing (via matchers)
to be included in formatting.  Instead, this change begins efforts to
instead include all files in format enforcement, relying instead on an
opt out methodology.
