vo/vulkan: sync recommended extensions and features from ffmpeg

Over time, the list of requested extensions and features has diverged from
ffmpeg (libhwcontext_vulkan), and while this isn't guaranteed to cause
problems, as it depends on driver behaviour, it definitely makes it hard to
compare validation errors between the two implementations.

This change requests the extensions/features which have not been incorporated
into any Vulkan version.
