[berkeley] Add setup stage to integration tests

[mrmr1993]

This PR modifies the integration test framework to run a setup function for each test before initialising the network. This PR also then lifts the expensive zkApp proving setup logic into these setup functions, so that integration tests don't spawn a network until the transactions are ready to be sent to it.
