Use WebScriptSource and WebFindInPageRequest from the WebKit API.

This change introduces some helper functions in glue_util.cc for efficient
conversion between WebString and WebCore::String when inside the implementation
of webkit/glue.  This is a temporary change since eventually all code in glue
that uses WebCore will be moved into the WebKit API implementation.

Instead of making the Chrome automation use WebFindInPageRequest, I decided to
introduce AutomationMsg_Find_Params as a copy of the old FindInPageRequest
structure.  That preserves the IPC protocol and avoids making the automation
library depend on WebKit.
