fix(render): render coronas and shadows for offscreen vehicles in drawingEvent

[CanerKaraca23]

Summary

Fixes vehicle headlight/taillight ground shadows and light coronas instantly vanishing and popping in when looking away from a vehicle or when the vehicle hull is off-screen.

Details

• Previously, ModelInfoMgr::OnRender was triggered solely inside MEEvents::vehRenderEvent.before (hooked into CVehicle::Render). When the vehicle's model bounding box leaves the camera frustum / viewport (GetIsOnScreen() == false), the game skips calling CVehicle::Render, causing projected ground shadows and light effects to instantly pop out of existence even when their ground area or light cones are clearly visible to the camera.
• Hooks Events::drawingEvent to iterate through active vehicles within reasonable camera distance ($120\text{m}$) that are not currently in the viewport (!pVeh->GetIsOnScreen()) and renders their light coronas and ground shadows.
• Skips BMX, boats, and trailers to prevent unnecessary processing.
