[mono][interp] Fix GetType called on ptr constrained to Nullable` (#61020)

* [interp] Fix GetType called on ptr constrained to Nullable`

We were statically optimizing this call to return the actual constrained class type, which is incorrect for nullables, because boxing of a nullable (as part of the constrained call) actually creates an object with the type of the nullable's value (or null if there is no value).

* Add test for GetType call on ptr constrained to nullable
