Document how to use Lua 5.4 and power patches

[4mmonium]

This commit adds documentation on how to use Lua 5.4 and documents the power patches provided by this new release. Most of the documentation for this comes from the readme (https://github.com/gottfriedleibniz/lua/blob/luaglm/README.md), 'as is' and the lua-users Wiki: http://lua-users.org/wiki/LuaPowerPatches#LUA_54_patches

I tried to not modify any of the documentation, only adding certain markdown styling and some extra explanation to specific terms which may not be known to new users.

Currently, FiveM is compiled with a different tree of LuaGLM that does not include all of the power patches gottfriedleibniz/lua:luaglm has and not all of them are enabled either :)

Thanks, I guess I will review this and remove any power patches that don't apply from the docs 😃
