This feature adds the platform attachment used for authentication to the WebAuthentication assertion response from the browser to RP following a successful authentication using a security key. This helps developers because it allows them to check if the current platform has an internal authenticator (isUVPAA is true) when the platform attachment is "cross platform" (as opposed to "platform"), and prompt the user to register their internal authenticator as well.
