[WGSL] Validate maximum array size
https://bugs.webkit.org/show_bug.cgi?id=270313
rdar://123852286
Reviewed by Mike Wyrzykowski and Alex Christensen.
Fix 2 issues with array sizes:
- the size was being treated as unsigned and only checking for 0, but according
to the spec the size can also be signed, and we should return an error for
negative values
- we also need to limit the maximum size of an array. the spec[1] says the
minimum
size we must support is 65535 bytes, but for now we just check for 65535
elements.
