vulkan: add support for encode and decode queues and refactor queue code

This simplifies and makes queue family picking simpler and more robust.
The requirements on the device context are relaxed. They made no sense
in the first place.

The video encode/decode extension is still in beta, at least on paper,
but I really doubt they'd change needing a separate queue family.
