Add vehicle suspension restoration and post-render handling

[QueryOfficial]

Summary

Privatize suspension line data for CAutomobile::PreRender, mirroring the existing collision hook pattern, so wheel render height is per-vehicle instead of shared per model.

After the PreRender wheel block, re-apply cached wheel_*_dummy component positions so setVehicleComponentPosition Z offsets are not overwritten every frame.

Motivation

Fixes #5007 and #1652.

#5007: When suspension handling is modified (setVehicleHandling, hedit, etc.), wheels render at the wrong height as soon as another vehicle of the same model streams in or recalculates handling. Physics is correct because ProcessVehicleCollision already swaps in per-vehicle private suspension lines via CopyGlobalSuspensionLinesToPrivate, but PreRender still reads the shared per-model CColModel suspension lines (“last writer wins”).

#1652: setVehicleComponentPosition on wheel dummies (wheel_lf_dummy, etc.) applies X but not Z, because PreRender overwrites wheel dummy Z from suspension lines every frame.

This change:

• Hooks CAutomobile::PreRender entry (0x6AAB50) to temporarily set the model’s suspension lines to the current vehicle’s private copy before wheel positioning runs.
• Restores the original per-model pointer at the existing post-wheel PreRender hook (0x6ABCFD in HOOK_Vehicle_PreRender).
• Registers a post-PreRender handler to re-apply script-set wheel dummy positions from CClientVehicle::m_ComponentData.

Test plan

• Spawn vehicle A (e.g. Infernus 411), lower/raise suspension via setVehicleHandling — wheels and body should match.
• Stream in vehicle B of the same model with default handling near A — A should still render with correct wheel height for all viewers (not just the owner).
• Re-apply suspension on A — B should not break visually (no last-writer regression).
• Repeat with a monster truck model if available.
• Run setVehicleComponentPosition(veh, "wheel_lf_dummy", x+1, y, z+10) — both X and Z offsets should be visible and stable while driving.
• Attach wheel.zip test resource from setVehicleComponentPosition does not work for Z axis on wheel dummies #1652 and confirm Z offset works.
• Verify unmodified vehicles / default handling still look and collide normally.
• Two clients: compare local owner vs remote observer for the same edited vehicle.

Environment tested: MTA:SA client (Windows), local + remote client scenario.
