Comparators - add default comparators

[ShaneBeee]

Description

This PR aims to add default comparators to Registry/Enum ClassInfos.
Skript in the past has had issues comparing 2 of the same object, ex:
if biome at player = plains:
Skript get's upset:

[12:09:09 INFO]: Line 18: (test.sk)
[12:09:09 INFO]:     Can't compare a biome with a biome
[12:09:09 INFO]:     Line: if biome at player = plains:

Rather than registering a comparator for each and every Registry/Enum entry, this allows them to dynamically register.
