Replaced include directives with import in .mm files


Renamed legacy autofill cvc component

This patch renames the Autofil CVC prompt for ios, before it gets
replaced by a new one. The old component now has "legacy" in its name
and the new one will have the original name. Once the new component is
launched at 100% in Stable(target milestone 106), the legacy component
will be removed.
