Java Edition removed blocks/Metadata variants

These existed due to the previous handling of block variations through metadata, rather than through block states or as separate IDs. Extreme values of these would produce unintended effects.

It was possible to place pumpkins and jack o'lanterns with no actual face using metadata values 5 and above. Their models became missing in 14w10a and they were removed in snapshot 14w26a like other unintended blocks.

In 17w47a, the faceless pumpkin was reintroduced as the default pumpkin block, with the existing pumpkins being retconned as carved pumpkins.
