Remove default keybinds for adjusting frameskips

These actions are not useful on modern hardware, as there are better
ways of adjusting emulation speed and VGA emulation is not as CPU
intensive as it was with old scalers.

On the other side, we can now reuse the Ctrl+F7/F8 keybinds for more
useful actions.

 Graphics emulation (speed up)
   VGA emulation is a demanding part of DOSBox in terms of actual CPU usage.
