Revert 96592 - Add scroll and gesture message filters for UIPI Flash. 

Flash forwards some window messages when it has no handler set. The only ones I've observed are WM_MOUSEWHEEL and WM_GESTURE (gestures are supported only on Win7). So, we need to allow these messages through the UIPI boundary. 

One important note is that I use per-process message filters on Vista, but per-window filters on Win7 or later (because they're supported). 

BUG=86810
TEST=None.
