Leszek Swirski 08955bb258 Revert "Reland "[runtime] Remove extension slots from context objects"" 
This reverts commit c48096d442.

Reason for revert: Flaky bot failures (https://bugs.chromium.org/p/v8/issues/detail?id=9744#c9)

Original change's description:
> Reland "[runtime] Remove extension slots from context objects"
> 
> This is a reland of c07c02e1c4
> 
> Original change's description:
> > [runtime] Remove extension slots from context objects
> >
> > Context objects have an extension slot, which contains further
> > additional data that depends on the type of the context.
> >
> > This CL removes the extension slot from contexts that don't need
> > them, hence reducing memory.
> >
> > The following contexts will still have an extension slot: native,
> > module, await, block and with contexts. See objects/contexts.h for
> > what the slot is used for.
> > The following contexts will not have an extension slot anymore (they
> > were not used before): script, catch and builtin contexts.
> > Eval and function contexts only have the extension slot if they
> > contain a sloppy eval.
