-----------
[WebGPU] Ensure staticThreadgroupMemoryLength does not exceed device
capabilities
https://bugs.webkit.org/show_bug.cgi?id=288735
rdar://145583179
Reviewed by Mike Wyrzykowski.
We currently compute the total size for all workgroup variables and validate
that
they do not exceed the device limit, but the validation was not performed
correctly
when an override variable was used as array size.
