Daniel Gibson 15ffd5df82 Disable broken idSIMD_SSE::UpSampleOGGTo44kHz() 
It corrupted the stack when called with buffers allocated on the stack
and numSamples that are not a multiple of four, apparently, by writing
4 floats too many, at least in the 22KHz Stereo case..

This caused the crash described in
  https://github.com/dhewm/dhewm3/issues/303#issuecomment-678809662

Now it just uses the generic C code, like all platforms besides MSVC/x86
already do.
