groth16 client on SimApp is created without keys

[rootulp]

Context

celestia-zkevm-ibc-demo/testing/demo/pkg/setup/initialise_groth16_client.go

Lines 61 to 63 in 2b34571

	func createClientAndConsensusState(genesisBlock, latestBlock *ethtypes.Block) (*cdctypes.Any, *cdctypes.Any, error) {
	// TODO: this clientState isn't created with a state transition verifier key or state inclusion verifier key.
	clientState := groth16.NewClientState(latestBlock.Number().Uint64(), []byte{}, []byte{}, []byte{}, genesisBlock.Root().Bytes())

Problem

The client on SimApp is not created with verifier keys for state transition, state inclusion, or a code commitment.

Proposal

The Info endpoint on the Prover contains these keys:

celestia-zkevm-ibc-demo/proto/prover/v1/prover.proto

Lines 16 to 20 in 758a711

	message InfoResponse {
	// TODO: add more info here as is relevant such as the circuit and state machine types
	bytes state_transition_verifier_key = 1;
	bytes state_membership_verifier_key = 2;
	}

so we should query that endpoint and supply the keys when creating the client on SimApp.

Note: we may need to expand the InfoResponse to include a code commitment over the circuit.
