Change array_from_fn signatures

[c410-f3r]

Superseded by #91286

Implementation

These functions are using the same inner code of other array methods and such feature already ensures a reliable execution.

Signature

Originally, indices returned by the callback were introduced as auxiliary parameters since arrays are hereditary indexed and known at compile-time.

But due to #75644 (comment) and #75644 (comment), no index will be returned to avoid further concerns or discussions.
