LibJS+LibUnicode: Generate all styles of currency localizations

Browse source 
Currently, LibUnicode is only parsing and generating the "long" style of
currency display names. However, the CLDR contains "short" and "narrow"
forms as well that need to be handled. Parse these, and update LibJS to
actually respect the "style" option provided by the user for displaying
currencies with Intl.DisplayNames.

Note: There are some discrepencies between the engines on how style is
handled. In particular, running:

new Intl.DisplayNames('en', {type:'currency', style:'narrow'}).of('usd')

Gives:

  SpiderMoney: "USD"
  V8: "US Dollar"
  LibJS: "$"

And running:

new Intl.DisplayNames('en', {type:'currency', style:'short'}).of('usd')

Gives:

  SpiderMonkey: "$"
  V8: "US Dollar"
  LibJS: "$"

My best guess is V8 isn't handling style, and just returning the long
form (which is what LibJS did before this commit). And SpiderMoney can
handle some styles, but if they don't have a value for the requested
style, they fall back to the canonicalized code passed into of().
