  avcodec/webp: Switch to ff_vlc_init_from_lengths()
  
  The earlier code would traverse over the code lengths
  mutliple times (namely max_length + 1 times - once to get
  the maximum length and once for each max_length to assign
  codes) before calling ff_vlc_init_sparse() (which may traverse
  them twice and sort them). The new code only traverses them once
  (+ the one time in ff_vlc_init_from_lengths()).

  avcodec/webp: Check more directly for invalid codes
  
  Don't rely on invalid codes leading to get_vlc2() returning
  -1, which then gets converted to an uint8_t, i.e. to 255
  and runs afoul of a length check later. After all, get_vlc2()
  could be changed to return something else which may
  be valid when cast to uint8_t.

  vulkan_decode: add STORAGE flag to output images
  
  In filtering, and SDR encoding, we use storage images.
  This fixes using Vulkan filters on Intel.
  Tested not to break anything on the three major vendors.

• vulkan : always enable ReadWithoutFormat/WriteWithoutFormat

  vulkan: always enable ReadWithoutFormat/WriteWithoutFormat
  
  This implements support for reading and writing storage images with
  no format.
  The issue is that we define our images as arrays, and arrays can
  only have a single type, which means that f.ex. NV12 needs two
  different images, R8 and RG8.
  
  The only driver known not to advertise support for the extension
  as a whole is Intel, because they have parial support for odd formats
  we never use. Therefore, just always enable it by default.
