LibUnicode: Generate currency unit-pattern number formats

These are used when formatting a number as currency with a display
option of "name" (e.g. for USD, the name is "US Dollars" in en-US).

These patterns appear in the CLDR in a different manner than other
number formats that are pluralized. They are of the form "{0} {1}",
therefore do not undergo subpattern replacements.
