Web Inspector: Implement snippets evaluation.

Source/WebCore:

Implemented snippet evaluation and adjusted breakpoints behavior when editing snippet.
Snippets are evaluated using separate compile and run.
Breakpoints are updated after compilation (once scriptId is available they can be set in debugger).
If separate compile and run is not supported by port or debugger is paused we fall back to evaluation in console.
