Fix incorrect new blockdata in EntityChangeBlockEvent (#9445)

Also fixes EntityBreakDoorEvent not having the correct 'to' block data

Also standardizes how to handle EntityChangeBlockEvent before a removeBlock or destroyBlock
call. Always use 'state.getFluidState().createLegacyBlock()' to get the new state instead of
just using the 'air' state.
