Call BlockEntity#load in new child types (#9340)

BlockEntity#load is responsible for loading the pdc data for block
entities. Some of the new block entities added by mojang do not call
their super method, preventing paper from loading the PDC, which
leads to a loss of data.

This commit adds the super calls to prevent this.
