Aliaksandr Kalenik 23885e7b4d LibWeb+WebContent+WebWorker: Drop display list player type selection 
WebContent no longer chooses between CPU and GPU display list players,
and the remaining callers always use Skia raster playback. Remove the
PageClient virtual and now-single-value enum, then play SVG image and
cursor display lists directly.
