This is a reland of commit b2f4cf3e01
Commented out deprecation for now.
Original change's description:
> Add class modifiers to `dart:convert`.
>
> The usual approach:
> Pure interfaces marked `interface`.
> Pure implementation classes marked `final`.
> Base classes marked `base` or nothing, and `mixin class` if reasonable.
> Combined X/XBase/XMixin where possible.
