LibJS: Make Value::to_property_key() return a JS::PropertyKey

Browse source 
Instead of returning JS::StringOrSymbol, which is a space-optimized type
used in Shape property tables, this now returns JS::PropertyKey which is
*not* space-optimized, but has other niceties like optimized storage of
numeric ("indexed") properties.
