Mark `slice::copy_from_slice` unstably const

Tracking issue rust-lang#131415

I used `const_eval_select` for runtime and const panic functions because const formatting isn't available yet.

@rust-lang/libs-api @rust-lang/wg-const-eval this function has been stable since Rust 1.9, and can be fully implemented using already-const-stable facilities (largely, ptr::copy_nonoverlapping). I would say it is ready for const-stabilization. :)

    pub const fn copy_from_slice(&mut self, src: &[T])

        T: Copy;
