Expliclty add modifyer settings for Shift/Ctrl/Alt

[PabstMirror]

Ref acemod/ACE3#4822
ACE was adding a keybind of [29, [false, false, false]] // 29 = CTRL/STRG key
But CBA keyhandler expects the control param bool to also be true [29, [false, true, false]]

The same problem also exists in the code that handles rebinding.
It would only add the base key with all modfiers set to false.

That code calls fnc_addKeybind, so we can solve both problems with this fix.

I know the rest of CBA (or ACE) usually doesn't do it that way, but I think instead of using the magic numbers for the DIK codes, we should use the enums from BI.

#include "\a3\ui_f\hpp\defineDIKCodes.inc" in this components script_component.hpp and then:

DIK_LSHIFT
DIK_RSHIFT
DIK_LCONTROL
DIK_RCONTROL
DIK_LMENU
DIK_RMENU
