Weapons: Update weapon menu

[JustGodWork]

Added function that keep track of ammo in ped weapon and refresh weapon menu

[Korioz]

Ammo updates were already tracked by the ui, i don't see the utility of this PR. Also note that this is really bad practice in terms of performance, the ui is rendered every tick and there is no need to fetch every tick esx weapons config.

If you drop a weapon with less ammo than at your connection you can pick it up with as much ammo as at the connection it's a flaw
