[WGSL] Generated metal source does not compile

Reviewed by Mike Wyrzykowski.

The GlobalVariablRewriter was using a HashSet to track reads, then using it to
insert the used parameters. However, since HashSets don't preserve order the
parameters could be inserted out of order. Replacing the HashSet with a
ListHashSet fixes the problem.
