feat(scripting/lua): add missing debug func (getlocal, setlocal, setupvalue) in lua debug sandbox

[eryxiz]

Goal of this PR

Add missing functions in debug library to new sandboxed lua debug.

• debug.setupvalue
• debug.getlocal
• debug.setlocal

How is this PR achieving the goal

Added the functions (debug.setupvalue, debug.getlocal, debug.setlocal) based on lua debug API.
The functions in the debug library can't access variables, code, or files outside the scope of a resource, so they shouldn’t have any impact on exploiting servers.

This PR applies to the following area(s)

ScRT: Lua

Successfully tested on

Platforms: Windows

Hey, these function were removed for a reason, I'll let a member of the cfx team confirm that but it's not planned to add them !

I understand that the reason for removing it is to prevent server exploits. However, as far as I know, the debug library currently operates within the scope of its own resource. So, I’m curious—how could someone exploit a server using these debug library functions when they’re limited to their own resource? This is different from the io library, which previously allowed full permission to read/write files anywhere.

Having these debug hooks can give users access to the scheduler, which isn't desired behavior.
