spirv reader: do not add duplicate constructed types

My last CL (https://dawn-review.googlesource.com/c/tint/+/49542) made it
so that AST nodes are re-created every type we resolve a spirv type id
to a tint type. This creates duplicate nodes, most of which are cleaned
up at the end of parsing. However, duplicates added as global
constructed types are not handled, so this CL makes sure we do not add
said duplicates.
