[FIX] Avoid multiplied hud release callback calls.

[Neloreck]

Changes

• Hoists g_pGameLevel->pHUD->net_Relcase(dit) out of the relcase callbacks loop into its own loop over destroy_queue in CObjectList::Update.

Notes

• The HUD notification was nested inside the m_relcase_callbacks iteration in CObjectList::Update, so pHUD->net_Relcase executed registered callbacks × destroyed objects times. Profiling a regular Call of Pripyat session with Tracy showed 847,150 CHUDManager::net_Relcase calls for 1,747 destroyed objects (~485 registered relcase callbacks).
• The misplacement predates OpenXRay .
• CHUDManager::net_Relcase only drops cached references to the destroyed object (HitMarker, m_pHUDTarget), so moving it after the callbacks loop is order-independent.
• Edge-case behavior change: with zero registered relcase callbacks the HUD was previously never notified at all; it is now always notified once per destroyed object.
