feat(protocol-kit): Add react native compatibility

[yagopv]

What it solves

Resolves #1026, #1027

How this PR fixes it

• Creating a new static method to create the passkey signer

const credential = window.navigator.credentials.create(requestJson)
const passkeySigner = await createPasskeySigner(credential)
const protocolKit = await Safe.init({ provider, signer: passkeySigner })

• Adding a getFn to the PasskeyArgType allowing the credential retrieval

type GetPasskeyCredentialFn = (
  options?: PasskeyCredentialRequestOptions
) => Promise<PasskeyCredential<PasskeyAuthenticatorAssertionResponse>>

• Implementing a specific decoder for public keys coming from React Native
