Compare for equality the specified `lhsString` and `rhsString` having the optionally specified `lhsLength` and `rhsLength`, respectively, _as if_ the strings were converted to lower case before the equality comparison. Return `true` if `lhsString` is equal to `rhsString`, and `false` otherwise. The behavior is undefined unless `0 <= lhsLength` and `0 <= rhsLength` (if specified), and `lhsString.size() <= INT_MAX` and `rhsString.size() <= INT_MAX` (if applicable). See {`bdlb_stringviewutil`} for an identically named method having the same semantics taking `bsl::string_view`.
