vo_opengl: change dwmflush option values 

Use a choice instead of an integer. This is incompatible, but I'm not

``dwmflush=<no|windowed|yes>``
Calls ``DwmFlush`` after swapping buffers on Windows (default: no).
It also sets ``SwapInterval(0)`` to ignore the OpenGL timing. Values
are: 0 (disabled), 1 (only in windowed mode), 2 (also in full screen).
are: no (disabled), windowed (only in windowed mode), yes (also in
full screen).
This may help getting more consistent frame intervals, especially with
high-fps clips - which might also reduce dropped frames. Typically a
value of 1 should be enough since full screen may bypass the DWM.
