Also adds a filter_line3 method which on aarch64 neon yields approx 30%
speedup over 2xfilter_line and a memcpy

Differences from v2:
coeffs moved into const segment
number of patches reduced

  avfilter/vf_bwdif: Add neon for filter_intra
  tests/checkasm: Add test for vf_bwdif filter_edge
  avfilter/vf_bwdif: Add neon for filter_edge
  avfilter/vf_bwdif: Add neon for filter_line Exports C filter_line
    needed for tail fixup of neon code
  avfilter/vf_bwdif: Add a filter_line3 method for optimisation
  avfilter/vf_bwdif: Add neon for filter_line3
