feat(authenticator): add react support for email mfa

[jjarvisp]

Description of changes

The purpose of this pull request is to expand authenticator support for email mfa.

The react authenticator now renders two new screens in response to the two new states added to the state machine in #6317. This update allows completion of email MFA based sign ins, email MFA setup, and the selection challenges that allow users to choose which MFA method to setup or sign in with.

1. selectMfaType -> SelectMfaType : CONTINUE_SIGN_IN_WITH_MFA_SETUP and CONTINUE_SIGN_IN_WITH_MFA_SELECTION
2. setupEmail -> SetupEmail : CONTINUE_SIGN_IN_WITH_EMAIL_SETUP

Need to pull down and verify some things but lgtm for the most part, left minor feedback mostly unrelated to implementation
