Store FTUE use case in an account setting

Your use case

What would you like to do?

Migrate the FTUE use case value from the local device to an account setting with the key FTUE.useCaseSelection

Why would you like to do it?

Web is now tracking that data in the account setting. See the implementation https://github.com/matrix-org/matrix-react-sdk/pull/8984

How would you like to achieve it?

Android is asking the use case question to user and storing that information on device. I would like to change the logic to that in the future all answers to this question are set in the account setting FTUE.useCaseSelection.

If the account that the user is logging into has already a value set, the FTUE use case selection screen should be skipped entirely.

Finally we should add a snippet of code that migrates the existing "on device use case selection" to the account setting.

Have you considered any alternatives?
