The user-set forced KF times are parsed *after* this deleted
loop and rescaled right after parsing.

Also clarify behaviour in case of specified timestamps

This patch rewrites the innermost loop of ff_yuv2planeX_8_neon to avoid zips and
horizontal adds by using fused multiply adds. The patch also uses ld1r to load
one element and replicate it across all lanes of the vector. The patch also
improves the clipping code by removing the shift right instructions and
performing the shift with the shift-right narrow instructions.

I see 8% difference on an m6g instance with neoverse-n1 CPUs:
$ ffmpeg -nostats -f lavfi -i testsrc2=4k:d=2 -vf bench=start,scale=1024x1024,bench=stop -f null -
before: t:0.014015 avg:0.014096 max:0.015018 min:0.013971
after:  t:0.012985 avg:0.013013 max:0.013996 min:0.012818

ff_filter_frame() always frees the frame in case of error, so we don't
need to free the frame after ff_filter_frame() fails.

This always happened at start with alternative boundary mode disabled.
The clipping only occurred if starting samples where high enough.

Clipping can happen when smoothed gain is higher than maximum
allowed gain factor for current frame and peak value option is
set to enough low value.

In case of failure, all the successfully set entries are stored in
*pm. We need to manually free the created dictionary to avoid
memory leak.

We still need to analyze frame for amplification at EOF.

Though this patch to fix ticket #6668, I belive it
is unnecessary to set SLICE_FLAG_ALLOW_FIELD flag to other
hwaccels(dxva, vdpau, etc). Please also refer the orginal comment
of 9cb150c9

Should also fix ticket #8442.
