Each core now has its own method directory, this makes it a lot easier and cleaner to both maintain and add new methods

When adding new methods, they should be defined in both the LuaFunctions.cpp and the respective Method.h file. Please also add the registry entry to the other cores' method registry, so we know what's implemented or not.

When a method is not implemented, it should point to a nullptr in the registry.

Fix CMaNGOS specific functions per expansion

CMaNGOS specific fixes

Also fixes issues where some methods were not registered like they should

-Remove all other core defines in headers
-Add CMaNGOS Cata compatibility

-Fix incorrect MaNGOS option for enable/disable of Eluna
-Update checkout actions to newer version since old version has deprecated functions
-Add CMaNGOS Cata fork to CI checks
-Upgrade CMaNGOS build environment to Ubuntu 22.04

CMaNGOS specific cleanups and CI update

Cata Preservation Project Changes

Add Cata Preservation Project support

-Add Cata Preservation Project(TC based) to CI check

Update CI build file

-Will need additional method header cleanup and adjustments

These are somewhat equivalent with the AzerothCore custom hooks, though they do work a little differently. Ensure to read the documentation if something differs.

This should fix having to cast the return value manually in scripts

Only the ones compatible with CMangos have been added

Modified from PR#314 since core hook catches all skills not just crafting

-As Foe found when converting to this system placing a function with a nullptr causes all the functions below it to not register properly and not work.
