Andreas Kling f6f791969d LibJS: Use Substring for regexp results ...

Return JS::Substring objects from the builtin regexp exec and split
paths instead of eagerly copying UTF-16 slices into new strings.
Matches, captures, and split pieces can now point back at the original
input until someone asks for the string contents.

Add focused runtime coverage for UTF-16 captures and regex split
captures so these lazy slices stay exercised.
