Fix window resize on software renderers

[natepiano]

Objective

On systems without a GPU (like VMs using Microsoft Basic Render Driver), resizing windows or switching to fullscreen crashes with a "surface is in use" error.

Fixes #22225

Solution

The issue was introduced in #21866 which removed cleanup code that hardware GPUs don't need, but software renderers require.

This fix restores that cleanup behavior specifically for software renderers (CPU device type), ensuring texture views are released before the window surface is reconfigured.

Changes

• In clear_view_attachments: Drop swap_chain_texture_view for windows with pending size/mode changes on CPU device types (runs before create_surfaces)
• In render_system: Remove ViewTarget components on CPU device types to release cloned texture views

Note: I'm not deeply familiar with bevy_render internals. If this approach or style isn't satisfactory, feel free to use this as an example of what can work and suggest changes. Happy to adapt!

Testing

Tested on Windows 11 VM with Microsoft Basic Render Driver (DX12 backend, CPU device type):

AdapterInfo { name: "Microsoft Basic Render Driver", vendor: 5140, device: 140, device_type: Cpu, driver: "10.0.26100.7309", driver_info: "", backend: Dx12 }

Test cases:

1. Minimal reproduction app (bevy_resize_repro) - simple App::new().add_plugins(DefaultPlugins).run()
2. Full integration with bevy_window_manager - window resize, fullscreen switching, borderless fullscreen all working

Platforms tested:

• ✅ Windows 11 VM (software renderer)
• ✅ macOS (hardware GPU)
• ✅ Linux (Asahi Linux on Apple Silicon)

Known limitation: The tests/window/resizing.rs example (which resizes every frame down to 1x1) still crashes on software renderers, but this is a pre-existing issue that occurred in 0.17.3 as well.

Happy to do additional testing if needed!

Thanks for catching this! We really appreciate user testing and your willingness to dig into fixing this. I've opened an alternative implementation that is a little less code here: #22254.
