hwcontext_vulkan: require storage properties to claim formats as supported 
This function dates back a long time ago, before vkfmt_from_pixfmt2.
When it was converted over, the thought was that this was far too
restrictive to demand storage images for each format.
With the new clever function, it makes sure to check that the compatible
subformats a format can be used as support storage capabilities.

This gets rid of fake support for RGB48/RGB96 which some implementations
offer but don't support using as storage images.

FFmpeg README

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

Libraries

  • libavcodec provides implementation of a wider range of codecs.
  • libavformat implements streaming protocols, container formats and basic I/O access.
  • libavutil includes hashers, decompressors and miscellaneous utility functions.
  • libavfilter provides means to alter decoded audio and video through a directed graph of connected filters.
  • libavdevice provides an abstraction to access capture and playback devices.
  • libswresample implements audio mixing and resampling routines.
  • libswscale implements color conversion and scaling routines.

Tools

  • ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
  • ffplay is a minimalistic multimedia player.
  • ffprobe is a simple analysis tool to inspect multimedia content.
  • Additional small tools such as aviocat, ismindex and qt-faststart.
