AK: Span: Fix signature of copy_to() and copy_trimmed_to().

Browse Source 
Two changes were made

 1. copy_to() and copy_trimmed_to() now return how many bytes were
    copied.

 2. The argument was changed to Span<typename RemoveConst<T>::Type>
    because the following would not work:

        ReadonlyBytes bytes0;
        Bytes bytes1;

        // Won't work because this calls Span<const u8>::copy_to(Span<u8>)
        // but the method was defined as Span<const u8>::copy_to(Span<const u8>)
        bytes0.copy_to(bytes1);
