Currently we use fake "debugger-paused" event hack to update execution line and call stack placards when source mapping is changed.
- add PresentationCallFrame.createPlacard method to create "live" placards that are updated on source mapping changes.
- remove PresentationCallFrame functionName, isInternalScript, and url getters.
- fire execution-line-changed event when selected call frame or source mapping is changed.
