Display a banner on the room list when 2 or more accounts are logged in, to let the user know
that they can swipe their avatar to switch account. The banner is stored as a new
Announcement.SwipeAvatarToSwitchAccount, and is dismissed when the user taps on it, or when
the user switches account by swiping their avatar.
The banner is displayed at the same place as the new notification sound banner, but never
at the same time.

Show a one-time bottom sheet on the home screen to announce that several
accounts can now be added (element-hq/element-meta#3349).
- Add `Announcement.MultiAccount`, which is never shown by default.
- AppMigration11 queues the announcement on application upgrade only,
and marks it as shown if the user already has several accounts.
- HomePresenter shows the bottom sheet only when the announcement is
pending, the MultiAccount feature flag is enabled and the user has a
single account.
- The "Add account" button hides the sheet, marks the announcement as
dismissed and starts the add account flow through the new
`HomeEntryPoint.Callback.navigateToAddAccount()`.

Cover the last remaining interfaces across features/announcement, cachecleaner,
call, contentscanner, createroom, knockrequests, lockscreen, rolesandpermissions,
startchat, userprofile and viewfolder, with their members and parameters.
Grouped into one commit rather than eleven near-empty ones, per the AGENTS.md rule
about tiny commits.
This completes every features/* api module.
