fix: add MFA for WebAuthn bindings

[J0]

What kind of change does this PR introduce?

We introduce bindings for MFA (WebAuthn) which consists of the following:

1. enroll() a. Single Step - enroll({factorType: 'webauthn'}) b. Multi-Step - enroll(factorType: 'webauthn, webAuthn{...})
2. challenge() -
3. verify() a. Single Step - verify({factorType: 'webauthn'}) b. Multi-Step - verify({factorType: 'webauthn', webAuthn{..}})

We also expose a few helper methods:

• identifyAuthenticationError
• browserSupportsWebAuthn
