ffmpeg | branch: master | Lynne <dev at lynne.ee> | Thu Oct  5 20:25:33 2023 +0200| [81cc0e13455baa5e6547df40dc5961d415d6fcd2] | committer: Lynne

hwcontext_vulkan: properly support STORAGE usage for mutliplane images

Fixes multiplane support on Nvidia.

Also, remove the ENCODE usage, even if the driver signals it as supported.
Currently, it's not used, and when it is used, it'll be gated behind
two extension checks.
