[vm] Reference type test stubs through Code; use the type as the owner of a type test stub. Directly referencing VM isolate instructions from an isolate snapshot causes the instructions to be copied into the isolate's image page because instructions do not use the indirection of the ref array. Duplicating the instructions caused TypeTestingStubFinder::LookupByAddresss to be unable to identity the duplicate copies of the VM isolate type testing stubs. Fixes identity of StubCode::*TypeTest broken by duplication in snapshot. Fixes generating AppJIT snapshots after loading from AppJIT snapshots. Fixes attribution of ticks for type test stubs in the AOT profiler.
