-----------
[WGSL] Structs containing runtime-sized arrays should not be nested
https://bugs.webkit.org/show_bug.cgi?id=290937
rdar://148035899
Reviewed by Mike Wyrzykowski.
The spec[1] says that all struct members should either have creation-fixed
footprint or the last member may be a runtime-sized array. However, a struct
that contains a runtime-sized array doesn't have creation-fixed footprint,
so it can't be used as a member of another struct.
