[WebGPU] Change checkedSum to use uint32_t rather than uint64_t in
RenderBundleEncoder
https://bugs.webkit.org/show_bug.cgi?id=278082
rdar://132393945
Reviewed by Dan Glastonbury.
It’s unclear from the specification
https://www.w3.org/TR/webgpu/#dom-gpurendercommandsmixin-draw that we should
not allow for these two values to exceed uint32_max when the buffer size
exceeds 4GB
The specification and Metal allow us to create buffers exceeding 4GB, though we
never do so in practice.
Change these to uint32_t as NSUInteger is 32-bits on some platforms.
