-----------
[WGSL] Atomics inside structs and arrays are not initialized
https://bugs.webkit.org/show_bug.cgi?id=267594
rdar://121062530
Reviewed by Mike Wyrzykowski.
In 273065@main we started explicitly initializing atomic variables in the
workgroup
address space, but not when the atomic was nested inside a struct or array. This
patch makes it so that we traverse the types of all variables in the workgroup
space, search for nested atomics and initialize them.
