[WIN] fix a couple dxva processor issues

Done in Open() to avoid spamming the log, as would happen in Render().

Some GPUs drop some progressive frames with a deinterlacing processor.

For those GPUs (or when an advanced setting is activated), change the Auto
mode to always use the prog. processor for progressive frames and deint. proc
for interlaced frames.

This comes at the expense of the switch speed between prog. and int. as the
processor must be recreated for each switch and there is no guarantee
about processor destruction/creation speed.

instead of opening the wrong one and switching later.

[WIN] fix joystick connect/disconnect issues.

Fixes access violation soon after unplugging a controller as XBMC and SDL
