deps(cargo): bump naga from 29.0.3 to 30.0.0

[dependabot]

Bumps naga from 29.0.3 to 30.0.0.

Release notes

Sourced from naga's releases.

v30.0.0

Major changes

Optional vertex buffer slots

This allows gaps in VertexState's buffers and adds support for unbinding vertex buffers, bringing us in compliance with the WebGPU spec. As a result of this, VertexState's buffers field now has type of &[Option<VertexBufferLayout>]. To migrate, wrap vertex buffer layouts in Some:

  let vertex_state = wgpu::VertexState {
      module: &vs_module,
      entry_point: Some("vs_main"),
      compilation_options: wgpu::PipelineCompilationOptions::default(),
      buffers: &[
-         &vertex_buffer_layout
+         Some(&vertex_buffer_layout)
      ],
  };

By @​teoxoy in #9351.

Integer shader I/O no longer defaults to @interpolate(flat)

To align with the shading language specifications, naga no longer assumes that integer-typed shader I/O should have flat interpolation, i.e., should not be interpolated. Even though flat interpolation is the only choice for integer I/O, it must be still specified explicitly.

WGSL:

 struct FragmentInput {
     @location(0) tex_coord: vec2<f32>,
-    @location(1) index: i32,
+    @location(1) @interpolate(flat) index: i32,
 }

GLSL:

-layout(location = 1) in int index;
+layout(location = 1) flat in int index;

By @​andyleiserson in #9321.

Empty buffer slices are now permitted

Creating a BufferSlice with a length of 0 no longer causes a panic.

Empty buffer slices can be:
