avfilter/vf_convolution: add float user_rdiv[4] to allow user options to apply correctly
Previously to support dynamic reconfigurations of the matrix string (e.g. 0m), the rdiv values would always be cleared to 0.f, causing the rdiv to be recalculated based on the new filter. This however had the side effect of always ignoring user specified rdiv values. Instead float user_rdiv[0] is added to ConvolutionContext which will store the user specified rdiv values. Then the original rdiv array will store either the user_rdiv or the automatically calculated 1/sum. This fixes trac ticket #10294, #10867.

avfilter/vf_convolution: add x86 SIMD for filter_3x3()
Tested using a simple command (apply edge enhance): ./ffmpeg_g -i ~/Downloads/bbb_sunflower_1080p_30fps_normal.mp4 \ -vf convolution="0 0 0 -1 1 0 0 0 0:0 0 0 -1 1 0 0 0 0:0 0 0 -1 1 0 0 0 0:0 0 0 -1 1 0 0 0 0:5:1:1:1:0:128:128:128" \ -an -vframes 1000 -f null /dev/null The fps increase from 151 to 270 on my local machine.
