[Test] Avoid verifying SILGen in cursor info test

Verifying SILGen causes `loadAllMembers` to be run, which in turn ends
up actually creating the parent PBD of each `VarDecl` in this test.
Without verification, we never deserialize that PBD and thus end up with
`class` instead of `static` as we should. That's incorrect, but it's an
existing failure (rdar://105239467).

Resolves rdar://109037827.
