This just bumps the required loader library version (libvulkan).
All device-related features, such as video decoding, atomics, etc.
are still optional and the code deals with their loss on a local level
(e.g. the decoder or filter checks for the features it needs, not
the hwcontext).
Bumping the required version essentially packs all maintenance
extensions which correct the spec rather than requiring to enable
them individually.
