We have warning suppressions in place assuming `Array.CreateInstance` will succeed if it's over reference types, same as `MakeGeneric`. There's however no analysis to ensure we have the type loader template for `__Canon[]`. This adds the analysis. The `reflection\GenericAttribute` test is currently failing because of this but we don't see it because it's marked RequiresProcessIsolation and we have a bug that we don't look at those tests at all. We had this bug for a while, but the test regression is more recent because we're getting better at not generating useless stuff. Template for `__Canon[]` is probably part of any bigger test because it's common.

Follow up to dotnet#100626. The original fix only worked for unoptimized builds because the list of templates doesn't survive from scanning phase (when we do dataflow) to codegen phase (when we no longer do dataflow). The test that this was supposed to fix is still failing in dotnet#100331.
