Add ListUnmanaged.print

[Argmaster]

This pull request adds print method to ListUnmanaged struct.
To avoid copying a leftover TODO from print function in List, it also makes an attempt on addressing it:

https://github.com/Argmaster/Cubyz/blob/ListUnmanaged.print/src/utils/list.zig#L213

// TODO: Is there no easier way to make this without an extra copy?

We might as well just leave it for different time tho

Resolves: #1425 (comment)

The way how more complex objects are printed is possibly fragile, and I don't think we should rely on it in tests.
Plus the dependence on Vec2d (which is going to change once Zig adds glsl-style vectors) is unnecessary.

[Argmaster]

Ok, would a array be fine? I would want something more than just a single value tbh

[IntegratedQuantum]

Why though, what do you intend to test with a composite type?

[Argmaster]

Ok, yeah I guess it doesn't make that much sense. I was somewhat aiming to test if realloc works and if weirder things can still be printed properly.

What about I replace it with a test that checks if .initCapactiy preserves the items pointer?
I would also test if items pointer changes when not using .initCapacity.
