media-libs/mesa: Add VIDEO_CARDS=nvk

* Add VIDEO_CARDS=nvk to build the Vulkan driver for NVIDIA GPUs
* Add all Rust submodules required by NVK
* Fix rust submodules not compiling on multilib system (see
* https://gitlab.freedesktop.org/mesa/mesa/-/issues/10490)

* Limit meson to < 1.4.0, to avoid a regression building Rust submodules
* Mesa bug report: https://gitlab.freedesktop.org/mesa/mesa/-/issues/10855
* Meson bug report: https://github.com/mesonbuild/meson/issues/12973

* Notes: since nouveau is also required make sure VIDEO_CARDS=nouveau is
  also set.
