Undefined variables `_thisEvent` and `_thisEventHandler`

[Timi007]

Tools (complete and add to the following information):

• HEMTT: 1.17.2
• Operating System: Windows 11

Description:
The magic variables _thisEvent and _thisEventHandler are flagged as undefined when they are used inside a function file that is not the same file as the eventhandler caller.

help[L-S13]: Undefined variable `_thisEvent`
  ┌─ addons/main/functions/fnc_onDraw.sqf:3:28

  │                            ^^^^^^^^^^ undefined variable

help[L-S13]: Undefined variable `_thisEventHandler`
  ┌─ addons/main/functions/fnc_onDraw.sqf:3:40

  │                                        ^^^^^^^^^^^^^^^^^ undefined variable

Steps to reproduce:

1. Create a CBA/ACE project with 2 function files, as shown in the example repo: fnc_addDrawEH.sqf and fnc_onDraw.sqf.
2. Build the project
3. Both _thisEvent and _thisEventHandler are flagged as undefined variables

Expected behavior:
Magic variables should not be flagged as unused variables.
