PublicKeyCredential: isUserVerifyingPlatformAuthenticatorAvailable() static method

The isUserVerifyingPlatformAuthenticatorAvailable() static method of the PublicKeyCredential interface returns a Promise which resolves to true if a user-verifying platform authenticator is present.

A user-verifying platform authenticator is a kind of multi-factor authenticator that is part of the client device (it is generally not removable) and that involves an action from the user in order to identify them. Common user-verifying platform authenticators include:

• Touch ID or Face ID (macOS and iOS)
• Windows Hello (Windows)
• Device unlock (fingerprint, face, PIN, etc.) on Android
