You don't need the va or vdpau drivers, they've been replaced by the libgallium packages so I think you're fine:

$ apt show mesa-va-drivers
Package: mesa-va-drivers
Version: 26.1.5-1
Priority: optional
Section: libs
Source: mesa
Maintainer: Debian X Strike Force <[email protected]>
Installed-Size: 35.8 kB
Depends: mesa-libgallium (>= 26.1.5-1)
Homepage: https://mesa3d.org/
Tag: role::shared-lib
Download-Size: 15.5 kB
APT-Sources: https://mirror.linux.org.au/debian unstable/main amd64 Packages
Description: Mesa VA-API graphics drivers - transitional package
  This transitional package ensures that older versions of mesa-va-drivers
  are replaced by mesa-libgallium during upgrades.
  .
  This is a transitional dummy package, it can be safely removed.
