  vulkan: add .buf_elems to FFVulkanDescriptorSet
  
  This enables users to specify a number that would be appended to
  the buf_content string.
  Saves users from needing to manually print to a string.
  
  An earlier commit tried doing this via .elems, but it was
  faulty, as this also incremented the total number of descriptors
  in the descriptor set.

  swscale/x86/rgb2rgb: optimize AVX2 version of uyvytoyuv422
  
  Currently the AVX2 version of uyvytoyuv422 in the SIMD loop does the following:
  4 vinsertq to have interleaving of the vector lanes during load from memory.
  4 vperm2i128 inside 4 RSHIFT_COPY calls to achieve the desired layout.
  
  This patch replaces the above 8 instructions with 2 vpermq and
  2 vpermd with a vector register similar to AVX512ICL version.
  
  Observed the following numbers on various microarchitectures:
