daggerfall-unity: init at 1.1.1

[l0b0]

Open source recreation of Daggerfall in the Unity engine

I could not figure out how to build this from source. The upstream build docs only explain how to do it from the Unity GUI, and there is no .csproj or .sln file in the project to use with buildDotnetModule or the like.

Closes #109385.

Tested:

• ./result/DaggerfallUnity.x86_64 starts the GUI and asks for the Daggerfall game files.

• nix-shell maintainers/scripts/update.nix --argstr package daggerfall-unity breaks badly. Diff:

  No idea what's going on there.

Remaining issues:

• strings ./result/UnityPlayer.so | grep '\.so' listed two libraries I could not find, but which did not seem to be necessary, at least for basic functionality: libGLES_CM.so.1, and libmono.so. Please add a comment if you know where to find them, or why they would not be necessary.

Can we use lib.makeLibraryPath here?

[paparodeo]

this might work tho the script expects an array of paths not a colon separated string
