Allow removal of "Connected to Windows" accounts from Edge profiles

Thanks for the feedback, we've heard this from other users too. Re: the connected to windows accounts, we are working to remove this but since it is cross group collaboration, it may take a while. We eventually would like to just sign you in with the profile account. 

Re: Adding an account only to the app, if you select the "This app only" option in the sign in flow where you are asked to manage the device, the account won't be added to the computer and nor will your device get managed.
