deps(lambda-rs-platform): Update wgpu and naga to v29.0.0

[vmarcella]

Summary

Upgrade naga and wgpu to 29.0.0 and update the lambda-rs-platform
wgpu integration to compile and behave correctly with the new APIs.
This includes wrapper changes required for instance creation, pipeline layout/depth state configuration,
surface creation, and surface frame acquisition/error handling.

Related Issues

None.

Changes

• Bump naga and wgpu to 29.0.0 in lambda-rs-platform and refresh Cargo.lock
• Update wgpu::Instance construction for the new InstanceDescriptor API
• Adjust pipeline layout creation to pass optional bind group layout entries
• Update depth/stencil pipeline state setup for wgpu 29 optional depth fields
• Update unsafe surface creation to use the new raw display handle shape
• Handle CurrentSurfaceTexture acquisition results from wgpu 29
• Add explicit Occluded and Validation surface error variants
• Remove a now-useless u64 conversion
