[WGSL] Struct offset can overflow
https://bugs.webkit.org/show_bug.cgi?id=275850
rdar://130092379
Reviewed by Mike Wyrzykowski.
We fixed a similar issue with the struct size overflowing in 279809@main, but I
missed
that the same could happen to the offset. The issue was that all the operations
were
already using Checked types, except rounding up the offset to the required
alignment,
which is where the overflow happened.
