Lynne 469cd8d7fa aacdec: convert to lavu/tx and support fixed-point 960-sample decoding ...

This patch replaces the transform used in AAC with lavu/tx and removes
the limitation on only being able to decode 960-sample files
with the float decoder.
This commit also removes a whole bunch of unnecessary and slow
lifting steps the decoder did to compensate for the poor accuracy
of the old integer transformation code.

Overall float decoder speedup on Zen 3 for 64kbps: 32%
