Fix sharing of mouse button state from mousekeys to ps2_mouse (#9124)

With this change, when ps2_mouse is disabled, mousekeys works as usual. With
ps2_mouse enabled, mousekeys button state is shared with ps2_mouse for clicking,
dragging, and scrolling, mousekeys clicks are produced by ps2_mouse only, and
mouskeys button state is transferred to mousekeys without generating clicks to
enable mousekeys dragging.
