Add ARM MVE SIMD optimization for resample_common in libswresample,
targeting Cortex-M processors with ARMv8.1-M Helium extension.

MVE and NEON are mutually exclusive (Cortex-M vs Cortex-A), so
compile-time selection is used. The assembly uses MVE tail-predicated
loops (wlstp/letp) which handle arbitrary filter lengths without
remainder loops. S32P support is added as MVE-only since vmlaldava.s32
provides native 32x32->64 bit accumulation not available in NEON.

Also rename resample.S to resample_neon.S for clarity.

Benchmarked on Cortex-M55, 200ms 2ch stereo, speedup vs C fallback:

      44.1->48k  48->44.1k  8->48k  48->8k  16->48k  48->16k

S16P: 1.70x 1.38x 1.77x 2.45x 1.75x 2.04x
FLTP: 1.32x 1.19x 1.32x 2.14x 1.34x 1.76x
