XWorld: some fixes

Fixes sound on most platforms, original root cause was bad menu code
as well as DMA callbacks taking too long. Worked around with smaller
chunk sizes. Permanent fix would include moving mixing out of the
callback. Rewrites input with code from rockboy/doom. Cherry-picks a
change from Gregory Montoir's `rawgl' to patch the code wheel
screen. Finally, adds a motion blur filter on select targets.
