Make integration tests easier to run locally

[TomAFrench]

Problem

Currently running the integration tests locally is a bit of a pain as it requires manually copying a number of files around and deploying contracts. We should have shell scripts for this so that the experience can be as simple as opening two shells (one for anvil and another for the javascript tests) and running two commands.

Happy Case

We should define shell scripts which can be run locally to simplify running these tests locally.

forge-init.sh: This should set up the foundry project for the verifier contracts. We should delete any unnecessary files from here as part of this so we're not compiling things we don't need.

noir/.github/workflows/test-integration.yml

Lines 219 to 220 in 4765c82

	- name: Create new Foundry project
	run: forge init --no-git --no-commit --force foundry-project

codegen-verifiers.sh: This should codegen the verifier contracts and pull them into the foundry project.

noir/.github/workflows/test-integration.yml

Lines 222 to 233 in 4765c82

	- name: Run codegen-verifier for 1_mul
	working-directory: tooling/nargo_cli/tests/execution_success/1_mul
	run: nargo codegen-verifier
	- name: Run codegen-verifier for main
	working-directory: compiler/integration-tests/test/circuits/main
	run: nargo codegen-verifier
	- name: Copy compiled contracts
	run: |
	cp tooling/nargo_cli/tests/execution_success/1_mul/contract/1_mul/plonk_vk.sol foundry-project/src/1_mul.sol
	cp compiler/integration-tests/test/circuits/main/contract/main/plonk_vk.sol foundry-project/src/main.sol

deploy-verifiers.sh: This would start up an anvil instance and deploy the contracts, writing the contract addresses to a json file.

noir/.github/workflows/test-integration.yml

Lines 214 to 217 in 4765c82

	- name: Run Anvil
	run: |
	anvil > /dev/null 2>&1 &
	sleep 10

noir/.github/workflows/test-integration.yml

Lines 235 to 243 in 4765c82

	- name: Forge build
	working-directory: foundry-project
	run: forge build
	- name: Forge deploy
	working-directory: foundry-project
	run: |
	forge create --rpc-url http://127.0.0.1:8545 --mnemonic "test test test test test test test test test test test junk" src/1_mul.sol:UltraVerifier --json > mul_output.json
	forge create --rpc-url http://127.0.0.1:8545 --mnemonic "test test test test test test test test test test test junk" src/main.sol:UltraVerifier --json > main_output.json

We can also have a overarching script to run all of these in order.

Alternatives Considered

We'll probably want to have a yarn command to rebuild any of the dependencies of the integration tests package.

Could we isolate solidity to it's own file? This way I can progress with work in more fine grained fashion.
