Update to wgpu-native v0.18.1.1

[almarklein]

closes #352

• Update the header files.
• Run codegen, fix parsing.
• Handle fixme's.
• Refactor canvas context, removing swap chain concepts in favor of wgpuSurfaceXX (check all).
• use new WGPUCompositeAlphaMode?
• What is FifoRelaxed present mode?
• Update tests and examples
• Fix that CanvasContext's don't clean up properly.
• Some calls can pass null pointer, check WGPU_NULLABLE and check for it. that nullable texture only applied to that particular situation, and we've got that covered.
• Check Device objects are not cleared on wgpu-native #405 -> nope, still leaks
• Check [Qt, Windows] Crash when switching from monitor to monitor with different DPI values #352 -> yes!
• Update release notes.
• Prepare a pygfx PR: Adjust to new wgpu-py pygfx#617
  • Adjust to API changes
  • Perhaps shader changes. Not needed
  • Can we use features like Float32Filterable rather than WGPUNativeFeature_TextureAdapterSpecificFormatFeatures -> not yet

After this is merged:

• Release wgpu-py.
• Merge pygfx-pr, and release pygfx.

As for #352, it looks like the warnings (when dragging a window from one monitor to another on Windows+Qt) cannot be avoided without breaking window resizing on other systems. Nevertheless, the window is not in a broken state anymore where a resize is needed to get it working again. In other words, the error messages are annoying but otherwise harmless.

almost done now 😅

Can we use features like Float32Filterable rather than WGPUNativeFeature_TextureAdapterSpecificFormatFeatures

The reason why I want this is that the latter is a native-only feature (not part of the webgpu spec). This means that using it also unlocks other stuff, and accidentally using that may cause downstream code to become incompatible with WebGPU.

I tried adding it to wgpu-native (gfx-rs/wgpu-native#322), but the feature is simply not implemented in wgpu-core yet. I'm looking into adding it there, but it will take some time before that lands in a new wgpu-native release.

Fixed the pypy memytest with another well-placed gc.collect 😉
