Drop renderer surface before window to fix segfault on close (Wayland)

[nicoburns]

Summary

Fixes #355 (segfault when closing the window on Linux/Wayland).

The GPU surface was outliving the window/display it was attached to. dioxus_native::launch_cfg_with_props kept an extra DioxusNativeWindowRenderer clone alive as a local:

let renderer = DioxusNativeWindowRenderer::with_options(...);
let config = WindowConfig::with_attributes(doc, renderer.clone(), attrs); // extra Rc clone
// ...
event_loop.run_app(application).unwrap();
// EventLoop (Wayland display connection) dropped here...
// ...then `renderer` (wgpu Surface referencing the dead wl_display/wl_surface) → SIGSEGV

Because the renderer is Rc-shared (and also provided as a vdom context), dropping the View on CloseRequested did not drop the inner renderer, so the wgpu Surface was only destroyed after run_app returned and the event loop / Wayland connection had been torn down — the driver then dereferences freed display memory.

Two changes:

• blitz-shell: impl Drop for View now calls self.renderer.suspend(), which releases the surface (RenderState::Suspended) while the window and event loop are still alive — robust regardless of outstanding renderer clones.
• dioxus-native: pass renderer into WindowConfig by value instead of keeping a stray clone alive past run_app.

Not reproduced locally (headless VM, no Wayland/NVIDIA); verified with cargo check, cargo clippy, and cargo test --workspace (all green).
