  1. [Strings] Escape strings printed by fuzz-exec 

    Previously we printed strings as WTF-8 in the output of fuzz-exec, but this
could produce invalid unicode output and did not make unprintable characters
visible. Fix both these problems by escaping the output, using the JSON string
escape procedure since the string to be escaped is WTF-16. Reimplement the same
escaping procedure in fuzz_shell.js so that the way we print strings when
running on a real JS engine matches the way we print them in our own fuzz-exec
interpreter.

Fixes #6435.
