Andreas Kling b6bef6b688 Libraries: Use UTF-16 for JS-visible runtime strings
Produce JS-visible string results as UTF-16 at their source, including
numeric formatting, BigInt and BigFraction formatting, URI encoding,
console formatting, parser errors, regular expression errors, Intl and
Temporal records, LibUnicode locale boundaries, and LibWeb bindings.

Handle fractional radix formatting through the UTF-16 builder view.
