change :validate_utf8=false to still emit utf8lcg/utf8-string-replacement

validate_utf8=true raises on bad input
validate_utf8=false now does not raise, but still produces valid
UTF-8 clean JSON by replacing characters.

the previous behavior of emitting bad JSON that was not UTF-8 clean
when validate_utf8 was false is dropped (and this was behavior only
of the C extension and not the ffi extension since the ffi layer must
do some scrubbing of its own).
