Make tvOS detail dismiss button opt-in and unstick more views

TVSidebarDetailContainer now exposes a showsDismissButton flag instead of
always attaching a Done toolbar item. The button is only enabled where a
view can end up with no focusable element on its own — Device
Capabilities (informational rows) and the Import Playlists/Subscriptions
flows.

Wrap Contributors, Translators, Acknowledgements, and Device Capabilities
destinations in TVSidebarDetailContainer for the consistent sidebar look,
and make the Translators/Acknowledgements rows focusable on tvOS by
wrapping them in Buttons so the Menu remote button can pop the stack.
