Instrumenting more of WM_ message processing for jank

This covers some Omnibox stuff, which is probably responsible for the jank in keyboard messages processing and drilling down some of issues.
There are some issues that require advanced investigations that are not included in this CL:
1. PeekMessage, which is probably processing hooks
2. DispatchMessage, maybe, having same issues
3. GetQueueStatus (!!!)
4. DefWndProc
