Revert "Make two settings sections visible for ephemeral guest profiles"

This reverts commit f354c627.

Reason for revert: Ephemeral Guest profiles will have the same UI as old (off-the-record) Guest profiles in M89.

Original change's description:
> Make two settings sections visible for ephemeral guest profiles
>
> - Make the "You and Google" and "Auto-fill" sections visible,
> when settings is based on an ephemeral guest profile.
> - The notion of Ephemeral Guest profiles (go/ephemeral-guest-profiles)
> is to be replacing the current guest profiles.
>
