Should native contracts be destroyable?

[AnnaShaleva]

Summary or problem description
The last part of #3210 that requires additional discussion. It's proposed to add destroy mechanism to native contracts so that native contracts management become very similar to the ordinary contracts. In future we may need native contracts to be destroyable, for example to replace one native contract with another new one.

The question is: should we support this functionality?

Where in the software does this update applies to?

I think that is not required, we can make it possible in a future when it's needed
