Support for zig 0.14.0

[mrexodia]

Not really for merging, just a continuation of #41 that builds locally with the latest zig release. I updated the default toolchain versions and fixed the build on macos, but it's just for reference for others.

#41 (comment)

This comment was not addressed and this is my first time writing Zig. The main issue I am running into is when building -Dexample=invocationhandler. It looks like the generation of classes.dex is failing because the path is absolute, when it should be relative. The confusing part is that the path is an absolute path somewhere in the build folder, but zig complains that it has to be relative to the project root?

Otherwise everything appears to build fine now.

I'm trying to take a look at the weekend!

Something to note is that nix develop doesn't work. I am looking into fixing it (I have pretty much no nix experience, so it might take a while)

My discoveries so far are that running nix flake update and pinning the zig version to 0.14.0 is getting me farther than without.
