Add implementation for WebDevToolsAgentClient::debuggerScriptSource....

Add implementation for WebDevToolsAgentClient::debuggerScriptSource. 

To be able to stop on top-level breakpoints We need to enable javascript debugger before 
any scripts are executed. That's why DebuggerScript.js contents should be retrieved synchronously.

I'm fine with the change, Pavel, do you think we should take this approach or
start moving devtools scripts from chromium resources into native WebCore files
as we discussed offline?

should this be added to platform_support_win.cc as well?
