Custom entity properties API (#5788)

Browse Source 
* Custom entity properties API

* Fix build fail

* Resolve comments

* Entity property registration improvements

* oops

* Add boolean and enum property sync API

* default value + no packet if value unchanged

* Don't send packet if no properties were updated

* small refactor

* the refactor, part two

* Move updateProperties to GeyserEntity

* Don't inherit properties from parent

* temp

* type-safe property updating

* Address review

* call the GeyserDefineEntityPropertiesEvent once, require specifying entity identifier instead of calling the event once for every entity type

* Migrate to identifiers (from custom items v2, thanks eclipse), remove duplicate logic

* fix test

* Merge 1.21.9, update copper golem entity property usage

* fixup javadocs
