Resolve array ** and ++ operators

[estevesnp]

Resolves the mult and cat operators for arrays and single pointers to arrays.
I could look more into the other cases (string literals, tuples and comptime known slices), but would take more time.

(partly) fixes #2105

I could also try to check if we could infer the size of the array by calculating it in cases where we know the actual number / array length on the right side

resolving the array length would be nice. You can use the resolveIntegerLiteral function to resolve the integer value of the right side.

These changes will need test coverage. I would suggest to add some tests to hover.zig.

should be done, thanks for the pointers!
