Reason for revert: causing crash

Bug: 378691634

Original change's description:
> [FedCM] Do not show spinner if input is protected
>
> In FedCM active mode, the spinner is set right away if an account row
> is selected. This results in seeing the spinner in some cases where the
> input protector kicks in. To solve this, we add a bool to
> OnAccountSelected so that it returns true when the verifying sheet is
> going to be used, which is when the spinner is desired. Care is taken
> so that if the spinner is not desired then no work is performed after,
> since the view may be deleted in other cases, like when showing the
> single account confirmation dialog.
