fix(gpu): resolve multiple WebGPU validation and runtime errors

- Fixed 'Invalid sample count 0' and 'Invalid anisotropic clamp: 0' by ensuring explicit pipeline and sampler states.
- Resolved WGSL parsing errors by replacing swizzle assignments in compute shaders.
- Fixed 'Texture destroyed' error in render_frame by reordering command submission and resource presentation/release.
- Added WGPU_DEPTH_SLICE_UNDEFINED for Windows compatibility and ensured consistent resolveTarget initialization.
- Cleaned up PassthroughEffect bind group layout mismatch and redundant string helper definitions.
- Verified all tests pass and applied consistent formatting.
