Add explicit IgnoreBOM and ErrorMode options to LibTextCodec decoders, and thread them through TextDecoder and TextDecoderStream. This lets Web-facing decoder APIs preserve BOMs when requested and use fatal error handling without post-processing decoded output. NB: RemoveBOM was renamed to IgnoreBOM as "RemoveBOM" is the name used by encoding_rs and was previously an implementation detail. The new name matches what is used by the encoding standard as it is now also used in LibWeb.
