feat(gta-core-five): raise the shop ped apparel item limit

[xalva98]

Goal of this PR

Raise the limit on how much addon clothing (SHOP_PED_APPAREL_META_FILE items) a server can use. Today, once a server reaches roughly 65,520 clothing items in total across all packs, players crash while joining — and removing any handful of items anywhere makes it work again, which is what shows it's a fixed limit and not a broken item.

That limit can't be raised with any convar or increase_pool_size, and it's hit well before the streaming pools run out — so in practice it's the real ceiling on how much clothing a server can add (around ~29.5k addon items on build 3095, since the base game already uses a large chunk of it). With it removed, raising the relevant pools finally lets servers add far more clothing. It should also help some setups that currently run into what looks like a "YMT limit," since this limit is reached sooner than that.

The change is opt-in and off by default.

How is this PR achieving the goal

The game keeps a single list of every clothing item, looked up by name. That list can only hold about 65,520 entries, and the release build doesn't guard against going past it — so once a server crosses that number the overflow corrupts memory and crashes the client. It happens on join because that's when every clothing pack loads and the list gets rebuilt.

This PR keeps its own, larger list on the side and points the game at it — both the code that rebuilds the list and the code that looks items up in it. When the fix is off (the default), everything behaves exactly as it does today.

Enable it server-side with:

setr game_enableExtendedApparelShopLimit true

Here's a clip of a large clothing pack (over 30k+ addon clothing) with the convar set to false

As you can see the game crashes as soon as the clothing packs load.

Here's a clip of that same clothing pack with the convar set to true:

The game fully loads in and all 1400+ clothing pieces for jackets are available (and more is possible probably)

PS: Even if my fix is not accepted I think everyone would highly appreciate this limit being increased to make full use of the pool size increases
