   avcodec/asvenc: Fix crash with unaligned pointers/linesizes
   This happens on systems where get_pixels really needs
   to be properly aligned, like ARMV7 or RISC-V. For these
   systems, 0401ca714a2714743573e27c384ffa810fd31a92 caused
   a bus error for the vsynth3-asv[12] tests, because
   the stride in these tests is unaligned. See e.g.
   https://fate.ffmpeg.org/report.cgi?slot=armv7-linux-gcc-13&time=20250527020548
   https://fate.ffmpeg.org/report.cgi?slot=rv64gcvb-linux-gnu-gcc&time=20250527001827
   
   It can also happen (even before said commit) if the pointers
   itself are unaligned, e.g. by using the crop filter:
   ffmpeg -filter_complex nullsrc=s=740x576:r=25,format=yuv420p,crop=w=720:x=2 \
   -c:v asv2 -f null -
   
   The alignment requirements for the frames passed to encoders are
   mostly undocumented; the only thing I could find is the documentation
   of AVFrame.linesize: "For video the linesizes should be multiples
   of the CPUs alignment preference". This means that the FFmpeg cli
   violates our API.
   
   Yet as the above command line shows, it can also happen with
   unaligned pointers and there does not seem to be a prohibition
   of this, so we need to handle this case. This commit does so
   by using get_pixels_unaligned when needed.
