  [WebGPU] incorrect value passed to resolveCounters

Reviewed by Tadeu Zagallo.

We were passing [0, querySet.count()) instead of [firstQuery, queryCount)
as the JS API requires.

This was incorrect and led to data being copied into the output buffer
from the wrong location.

* LayoutTests/fast/webgpu/nocrash/fuzz-287761-expected.txt: Added.
* LayoutTests/fast/webgpu/nocrash/fuzz-287761.html: Added.
Add regression test.
