Deleting the field possible_number_pattern from the phone number metadata proto. (#1830)

This hasn't been used for a long time.
Deleted all methods that refer to this, and removed the field from the test XML file (somehow this was missed) as well.
Regenerated jars - because we no longer write a boolean to indicate whether we have the possible number pattern or not all the java metadata files needed regenerating too.
Deleted some data from the js phone metadata implementation that isn't used by js as well (national number matcher pattern)
