fix(gamestate/server): add array bounds checks and fix native decl.

[tens0rfl0w]

Goal of this PR

This PR addresses two issues: missing bounds checks that allowed reading out-of-bounds memory, and a missing parameter in the native declaration of GET_VEHICLE_DOOR_STATUS.

How is this PR achieving the goal

• Introduced checks to ensure that array indices are within valid bounds before accessing data, preventing out-of-bounds reads.
• Updated the native declaration of GET_VEHICLE_DOOR_STATUS to include the missing doorIndex parameter.
• Corrected array size for doorPositions in CVehicleGameStateNodeData.
