This is a backport of v1.10.0 (1.20.2), with some notable differences:

• The NBT operation/operator data types are still re-using vanilla's NBT operation/operator classes.
• The modify_riding_position and modify_passenger_position power types are currently not re-implemented due to its dependence on a method that only existed in Minecraft versions 1.20.2 and above for its implementation.
