lang: Support languages that speak the units before a numerical value

Previously, it was hardcoded to the english convention of units-last, so
"100%" would be voiced as "one hundred percent".  This adds a new
language flag that makes the units be voiced first, ie "100%" will be
voiced as "percent one hundred".

So far only the Chinese-traditional and Chinese-simplified languages
utilize this feature (taken from an old ticket, FS#10340) but I'm sure
others would want this feature too.
