[COC] Support usage of multiple spawn_loadout sections in character descriptions.

[Neloreck]

Allows addition of sections spawn_loadout, spawn_loadout2 ... spawn_loadoutN for stalkers items randomization.
Definition of rifle + pistol character description becomes simpler and more readable.

#1529

Changes

• Similar to CoC support few loadouts in character description
• Support silencer/scope probability to spawn
• Add callback for script based handling of loadouts (https://github.com/revolucas/CoC-Xray/blob/master/src/xrGame/alife_object.cpp#L29)
• Respect count value in loadouts for non-weapon items

[ChugunovRoman]

xr_sprintf(loadout_section, "spawn_loadout%d", loadout_index);

Can it be updated? Or it has been already merged as a part of #1751 (or it does add new feature)?

[Neloreck]

Will take a look later.
Seems like in latest changes str was updated to static constexpr cpcstr and it will need some tweaks to resolve conflicts and allow reading of incremental loadout sections.

@Xottab-DUTY
Since CoC part is merged, I can also copy-paste this part from CoC source:

luabind::functor<bool>	funct;
	if (ai().script_engine().functor("ai_stalker.CSE_ALifeObject_spawn_supplies", funct))
	{
		if (funct(this, ID, ini_string))
			return;
	}

Anomaly just leaves commented out spawn loadouts and handles spawn on se_object spawning

function on_creation(se_npc)
	if not (se_npc) then
		return
	end
	
	if skip_npc[se_npc:section_name()] then
		print_debug("NPC Loadouts | SKIP | %s", se_npc:section_name())
		return
	end
	
	-- Get NPC info
	local squad = se_npc.group_id and se_npc.group_id ~= 65535 and alife_object(se_npc.group_id)
	local player_id = squad and squad.player_id
	local squad_name = squad and squad:section_name() or "na"
	local comm = se_npc:community()
	local rank = ranks.get_obj_rank_name(se_npc)
	local data = utils_stpk.get_stalker_data(se_npc)
	local visual = data.visual_name or "na"
	
	create_item_on_npc(se_npc, squad_name, comm, rank, visual, player_id, "primary")
	create_item_on_npc(se_npc, squad_name, comm, rank, visual, player_id, "secondary")
	create_item_on_npc(se_npc, squad_name, comm, rank, visual, player_id, "extra")
end

• Added CoC callback for custom lua generation of loadouts
• Added util to check probability of flags (like scope=0.25, silencer=true, launher) and used it for all 6 places
• Changed variables/comparison to use same style, can change to snake_case if needed

In theory it should work with original, CoC and anomaly scripts/ltx loadout variants

Got this result from spawning 6 NPCs with wpn_lr300=1, scope=0.5, silencer=0.5, launcher=0.5\n
