#61441 Allow user to set email ID before setting up 2FA

What does this MR do?

The MR is to resolve the issue #61441 (moved).

It checks that if the user has temporary email ID assigned or not. If the temporary email ID is assigned then it bypasses the two-factor requirement check. That will allow users to associate email ID first with their account and it will not go in continuous redirect scenario as explained in #61441 (moved)

There are no tests added yet. I read somewhere in the docs to start a PR as early as possible. That is why doing it right away to confirm that I am on the right path.
