-----------
[WebGPU] Switching pipelines does not zero out dynamic offsets from prior
pipeline
https://bugs.webkit.org/show_bug.cgi?id=285828
rdar://142761614
Reviewed by Cameron McCormack.
When calling resize() on a Vector, dynamic offsets from a previous draw
call could remain in the dynamic offsets Vector. Ensure they are zero'ed instead
by using Vector's ctor instead.
No change needed for RenderBundles since render bundles save all the dynamic
offsets across all draw calls into a single buffer.
* LayoutTests/fast/webgpu/nocrash/fuzz-285828-expected.txt: Added.
* LayoutTests/fast/webgpu/nocrash/fuzz-285828.html: Added.
Add regression test.
