feat(lua): additional, mostly creature class family, bindings

[AluminumAlman]

Summary

SUMMARY: Infrastructure "A lot of creature class family functions and members exposed to Lua"

Purpose of change

Building on top of #2216, a whole bunch of functions for creature, character, avatar and NPC are now exposed to Lua, with other bindings in order for the aforementioned bindings to work, and a few other miscellaneous bindings.

Describe the solution

In order to bind most of the creature class family's methods and members to Lua, the types used/returned had to be bound to Lua first, which required additions to them, most of them covered by doc/LUA_SUPPORT.md. By using (mostly) regex, header files of the classes in question were formatted step-by-step so that it wouldn't be as tedious as doing it manually, however looking over the result was necessary sometimes. Preprocessor macros were made to make typing bindings manually less of a hassle when the regex processing didn't work.

Testing

• Project builds (on my machine);
• Ran some bound functions through the Lua console to make sure that they worked;

Additional context

• Some of the bindings are commented out, whether it be because they are unnecessary, throw errors when building or "I did not want to confuse Lua modders with too many bindings" (I was lazy to uncomment them). If need be, those can (hopefully) be uncommented easily.
• No regression tests were done; get_character_name was replaced by a member of a class, therefore there may be some broken Lua mod(s) with the current state of the PR.

Closing because after commit 18d9778, building fails at the linking stage, with the linker freezing with no error. Will remake this PR in another, more up-to-date, branch.

EDIT: #3990 is the new PR.
