Adapt ICU 59 API update to Doclava changes.
Add methods that were missing from the previous API update because the
update-api version used for that had different behaviour from the
current one.
Specifically overrides for methods that differ only in sychronization
are now considered API-worthy and weren't before (b/62576297).
All methods added in this commit are methods that exist in the base
class without synchronization and are synchronized in the class they are
now being added in.
