Fixes#23625.
The U+FE0F character was appearing in the data supplied by
emoji-datasource-google, but isn't in the CLDR data. By
removing that variation selector character, all remaining
emoji (that were previously marked as "not found in custom
emoji name maps, but also not found in CLDR data. Skipping.")
are now supported.
This script pulls from our previously custom-written emoji strings
and fills in the rest from CLDR. It also removes 4 custom emoji which
collide with some of the new CLDR names (they will now just be called
by their CLDR name).
