This commit adds C implementations of 6-tap motion compensation filters
for 4 of the 9 separable configurations that do not contain SHARP e.g.
REGULAR_REGULAR, REGULAR_SMOOTH, SMOOTH_REGULAR AND SMOOTH_SMOOTH.
Ideally this would have no impact on binary size as meson defaults to
-Dtrim_dsp=true which uses dead code elimination to remove the C code.
However, the allowed CPU instructions are SSE2 for x86 and NEON for arm
and SSE2 mc routines were removed in 85c1639 while arm has never had
SIMD for any of the scaled functions, thus the C routines are included.
Also, on riscv and ppc architectures there are *only* C implementations
and the 6-tap routines provide a meaningful speed-up when decoding the
600 frame Bosphorus_1080p_8bit.ivf file described in e51f437:
