Put Web Inspector's JS debugger hooks under ENABLE(JAVASCRIPT_DEBUGGER)

[Peter Kasting]

In the Chromium port, we can't yet use the JavaScript Debugger.  To obviate the need to fork files, I plan to place the hooks to support the debugger under ENABLE(JAVASCRIPT_DEBUGGER), which will be on by default.  This flag can go away eventually once we can support the debugger in our port.

Notable points to review:
* Make sure I didn't erroneously cover any non-debugger functions.
* If there are more helper functions, #includes, etc. that can also go under this #if, I may have missed them; feel free to point that out.

I wonder if it would be better to make startDebugging() and stopDebugging() (and probably some of the other InspectorController functions) be no-ops when the debugger is disabled. That would allow us to add fewer #ifdefs, I think. But I guess that's inconsistent with how we normally use the ENABLE() macro.
