dhong44 d0abad27ab Fix the mousekey scrolling (#9174) 
Mousekey scrolling should have a separate repeat variable
to keep track of scrolling acceleration, instead of being
tied to mouse movement scolling in mousekeys. The send function
should record when the last movement was made since this is
when movement is actually sent. Doing this fixes the bug where
the initial press of a mousekey scroll button causes a double scroll.
