LibJS: Begin implementing Intl.NumberFormat.prototype.format

Browse source 
There is quite a lot to be done here so this is just a first pass at
number formatting. Decimal and percent formatting are mostly working,
but only for standard and compact notation (engineering and scientific
notation are not implemented here). Currency formatting is parsed, but
there is more work to be done to handle e.g. using symbols instead of
currency codes ("$" instead of "USD"), and putting spaces around the
currency symbol ("USD 2.00" instead of "USD2.00").
