Revert of [inspector] console get all information from inspector when needed...

Revert of [inspector] console get all information from inspector when needed (patchset #5 id:80001 of https://codereview.chromium.org/2784713002/ )

Reason for revert:
One more failed layout test.

Original issue's description:
> [inspector] console get all information from inspector when needed
>
> With this CL we don't need to store reference to InspectedContext inside of JavaScript console object and able to get all required information from callback data.
> It allows us to implement console methods without taking in account how and where we create and store these methods:
> - later we can move console object implementation to builtins..
> - ..and install command line API methods smarter.
