Integration test for zkapps with changing VKs

[deepthiskumar]

1. zkApp transaction that updates VK and refers to it in subsequent account updates (should be accepted into the pool and included in a block with Applied status)
2. zkApp transaction that updates Vk but refers to older VK in subsequent account updates (should be accepted into the pool and included in a block but with Failed status, the failure being invalid-proof)
3. Enqueue another zkApp transaction that has a proof against the new VK immediately after (2) is enqueued. The transaction should be accepted (VK looked up from the refcounted table) and included in a block with `Applied status)
