4fdacf4cdb imdct15: remove the AArch64 assembly 
Prep work for the next commit, which will add a new FFT algorithm
which makes the iMDCT over 3x faster than it is currently (standalone,
the FFT is with some framesizes over 10x faster).

The new FFT algorithm uses the already thouroughly SIMD'd power of two
FFT which already has SIMD for AArch64, so users of that platform will
still see an improvement.

The previous FFT+SIMD was barely 2.5x faster than the C versions on these
platforms.
