rebase CL 2044170 part 1:
Adds a new `FrameNavigationControl::JavaScriptMethodExecuteRequest`
method. Previously every message was turned into an object literal in a new
script and sent to the renderer process executing the
front-end, which was very costly and leads to a lot of unnecessary
script executing in the V8 engine.
