Ilya Yanok 936cdeeb2f Revert "Reland "Add more interface and final modifiers to dart:core.""

This reverts commit e293eb809d.

Reason for revert: Breaks G3.

Original change's description:
> Reland "Add more `interface` and `final` modifiers to `dart:core`."
>
> This is a reland of commit 4f8333e80e
>
> Blocked on Flutter patch: https://github.com/flutter/engine/pull/40175
>
> Original change's description:
> > Add more `interface` and `final` modifiers to `dart:core`.
> >
> > Make intent explicit for classes which are intended as interfaces,
> > or which are not intended to be subclassed.
> >
> > Mainly classes which are pure interfaces are marked as such,
> > and platform-specific classes not intended for subclassing
> > are made `final`.
> >
> > The `final` classes includes `BigInt`, which is written to assume
> > that arguments inherit its private members
> > (it runs `_ensureSystemBigInt` on arguments).
> >
> > It also includes the `Expando`, `WeakReference` and `Finalizer` classes,
> > which are just intended as stand-alone implementation classes for accessing
> > platform-specific functionality.
