Fix building the WMF plugin

9df63fd6 made it possible to build only the audio decoder service from
the WMF plugin. When that change was merged to 5.8 it was not ported
to the new configuration system.
Added a new '-mediaplayer-backend' configure option to select the media
player backend to use on Windows. '-wmf-backend' is kept for backward
compatibility.
