Example: 

new TextDecoder('iso-8859-3', {fatal:true}).decode(new Uint8Array([190]))

Expected: throws
Actual: Produces U+FFFD

In contrast, this throws correctly:

new TextDecoder('utf-16', {fatal:true}).decode(new Uint8Array([0]))

Text Encoding: Fix "stop on error" for ICU-based codecs

Handling of errors when the "stopOnError" flag was set in
TextCodecICU::decode() was incorrect; the replacement character was
always emitted instead. Align the initialization of the ICU error
callback with what i18n/icu_string_conversions.cc does.
