machenbach a2f2e913f8 Revert of [debugger] debug-evaluate should not not modify local values. (patchset #2 id:20001 of https://codereview.chromium.org/1513183003/ )
Reason for revert:
[Sheriff] Layout test changes.

Original issue's description:
> [debugger] debug-evaluate should not not modify local values.
>
> Debug evaluate no longer writes back changes to the replicated
> context chain to the original after execution. Changes to the
> global object or script contexts still stick. Calling functions
> that bind to the original context chain also have their expected
> side effects.
>
> As far as I can tell, DevTools is not interested in modifying
> local variable values. Modifying global variable values still
> works as expected. However, I have not yet removed the old
> implementation, but merely keep it behind a flag.
