[WebGPU] RenderPassEncoder::beginOcclusionQuery will crash when offset%8 != 0
https://bugs.webkit.org/show_bug.cgi?id=254177
<radar://106959317>
Reviewed by Myles C. Maxfield.
In QuerySet.mm, Device::createQuerySet already creates a buffer
with size that is a multiple of 8.
-[MTLRenderCommandEncoder setVisibilityResultMode:offset:] requires
offset to be a multiple of 8. It is the offset into the buffer.
queryIndex is the index of the visiblity query. Each index is offset
8 bytes in the buffer.
So we can simply multiply the index by 8 here.
