🪚 OmniGraph™ Repeatable setup for Endpoint & Uln302 deployment & configuration

[janjakubnanista]

In this PR

• Two new packages, not intended for publishing (at least initially):
  • @layerzerolabs/protocol-utils containing wiring logic for EndpointV2 and Uln302. The Uln302 wiring logic is not split between ReceiveUln302 and SendUln302, it is left to the consumer to provide configuration that only pertains to the specific type
  • @layerzerolabs/protocol-utils-evm containing EVM SDKs for EndpointV2 and Uln302
• setupDefaultEndpoint test utility in @layerzerolabs/ua-utils-evm-hardhat-test that can be and is used to spin up a fresh endpoint & ulns before every test in order not to persist state between tests. This replaces the default endpoint deployment that was previously done before running the whole test suite

To setup a fresh endpoint & Ulns in your tests, you can now simply add this to your test suite:

beforeEach(async () => {
    await setupDefaultEndpoint()
})
