AK+LibUnicode: Implement String::equals_ignoring_case without allocating

Browse source 
We currently fully casefold the left- and right-hand sides to compare
two strings with case-insensitivity. Now, we casefold one code point at
a time, storing the result in a view for comparison, until we exhaust
both strings.
