[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.
