Feature: Implement a Passkey SignatureValidator factory (#306)

This PR is a partial solution for #288. What needs to be added is a proper test suite for the factory. It only has one migrated end-to-end test from the 4337 module package. What was done: - Introduce `ICustomECSignerFactory` and `ICustom256BitECSignerFactory` interfaces for custom signer factories. The first is generic and should work with signing algorithms of any key length, while the second is optimized for EC signing and 256-bit key sizes. The first one is not used in the project and is kept as an example or for future reference. - Add the `WebAuthnVerifier` and make it use the new P256Library introduced in #298 - Migrate the `SafeSignerLaunchpad` contract and make it implement the `ICustom256BitECSignerFactory` interface thus making it `Safe256BitECSignerLaunchpad` - Migrate and adjust the end-to-end test from the 4337 module for the launchpad To be done: - Remove the migrated contracts from the 4337 package
