feat(contracts): transparent proxies and el genesis (piplabs#165)

* Change UUPS by TransparentUpgradeableProxy, use etching to generate initial contracts

* etch all the contracts

* git ignore local dumps

* fix contracts/script/EtchInitialState.s.sol, use it also as setup for tests

* fix GenerateAlloc for UpgradeEntryPoint, add allocations and test upgradeability

* lint and cl fixes

* temporarily disabled solhint in CI/CD

* temporarily remove run_solidity_lint

* temporarily remove lint form workflow

* remove need for env function in test
