[WebGPU] pathological integer wrap in createVertexDescriptor
https://bugs.webkit.org/show_bug.cgi?id=283200
rdar://136576990
Reviewed by Tadeu Zagallo.
Migrate += to using checked math in a case which should not overflow.
Test: existing tests pass. No new test because overflow test would
require vector with > 2^32 - 1 elements and we would run out of memory
first given the elements are each 16 bytes so ~64GB of memory from that
allocation alone.
