[WGSL] Parser can still stack overflow
https://bugs.webkit.org/show_bug.cgi?id=281491
rdar://137684585
Reviewed by Mike Wyrzykowski.
We already have recursion depth checks in the parser, but in some cases it takes
multiple stack frames in a recursion to hit the check, so it's still possible
for
it to overflow. To try and remedy add an extra check to try and limit the number
of frames in such recursions.
