[PATCH 0/2] VVC: AVX2 planar intra prediction

This series adds an AVX2 implementation of the VVC planar intra
prediction kernel, which currently has no SIMD implementation on any
architecture. Only 8-bit is implemented here; the 10 and 12-bit paths
still use the C reference and can be added in a follow-up.

Patch 1 adds a checkasm test so the second patch can be verified. The
test iterates 8, 10 and 12 bit, so it will also cover the higher depths
once SIMD for them is added.
Patch 2 adds the 8-bit kernel and wires up x86 dispatch.

Tested on AMD Ryzen 7 5825U:
  - checkasm passes: the 8-bit AVX2 kernel matches the C reference
  - fate-vvc passes, unchanged from before the series
  - framemd5 output is identical with and without -cpuflags 0
