[DevTools] Changed checks in InspectorConsoleWindow::autogenerateMetadata

[DevTools] Changed checks in InspectorConsoleWindow::autogenerateMetadata

Removed part of the check related to the type of agent. This test was important when the engine used another JS engine.

ScriptState no longer participates in check. And now only used to obtain the ID of context.

The method createScriptCallStackForConsole now uses a method call createScriptCallStack forming a stack which is able to receive an empty stack and not adds a fake frame.
