+hwcontext_vulkan: remove optional encode/decode extensions from the list
+
+They're not currently used, so they don't need to be there.
+Vulkan stabilized the decode extensions less than a week ago, and their
+name prefixes were changed from EXT to KHR. It's a bit too soon to be
+depending on it, so rather than bumping, just remove these for now.
+
+Upstream-Status: Backport [https://git.ffmpeg.org/gitweb/ffmpeg.git/commitdiff_plain/eb0455d64690]
