Replace ptr::read-based field consumption with Option<T> + take() for sync primitives, GPU allocations, and the allocator itself. The prior pattern left bitwise-duplicated values in the original fields, so Rust's automatic field drop after Drop::drop returned freed the same heap buffers (Vec backings inside SyncPrimitives) and Allocations twice. The allocator is now explicitly dropped before destroy_device so its own Drop impl, which releases vk::DeviceMemory blocks, runs while the logical device is still valid. Swapchain image views are also now destroyed before the swapchain, as required by the Vulkan spec.
