google-chrome: fails to initialise vulkan implementation due to missing libvulkan.so.1

[JohnRTitor]

Describe the bug

If Vulkan in Chrome is enabled via CLI args or chrome://flags, Chrome still fails to launch it's vulkan implementation, falling back to OpenGL.

Steps To Reproduce

google-chrome-stable --use-vulkan --enable-features=Vulkan

Or directly run:

NIXPKGS_ALLOW_UNFREE=1 nix run --impure nixpkgs#google-chrome  -- --use-vulkan --enable-features=Vulkan

Expected behavior

Vulkan is enabled, and working.

Screenshots

Output from chrome://gpu:

We do copy all the needed files from the deb package.

And libvulkan.so.1 exists in $out/share/google/chrome/.

[JohnRTitor]

Finally figured out the issue, bundled libvulkan.so.1 was not working properly.
Replacing it with vulkan loader's libvulkan worked like a charm! Did it like electron-bin. Commited part of #346215.

Nice work, thank you!
