Implement app_v2 wiring

[fmorency]

Using app_v1 is causing the TestAppImportExport simulation to fail in CosmosSDK v0.50.6.

I see similar behavior in this application.

KV stores are different: 27 key/value pairs in store A and 0 key/value pairs in store B

The issue doesn't occur when using app_v2 wiring in CosmosSDK. Implement app_v2 wiring in this application and see if it fixes the problem.

It appears that this module depends on wasm which depends on ibc. Both wasm and ibc are incompatible with v2 wiring.
