avcodec/mpegaudiodsp: Make initializing synth windows thread-safe
These arrays are used by the Musepack decoders, the MPEG audio decoders as well as qdm2 and up until now, these arrays might be initialized more than once, leading to potential data races as well as unnecessary initializations. Therefore this commit ensures that each array will only be initialized once. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
