* Show PageActionView for partitioned storage tab in location bar
When the current tab uses a Brave container (partitioned storage), show the
page action in the location bar with the container's icon, name, and
background color from ContainerModel.
- Register kPartitionedStorageActionIconType and enable it in the location
bar only when ENABLE_CONTAINERS and the Containers feature are on.
- Add PartitionedStoragePageActionController that resolves the tab's
container via GetContainerIdForWebContents and ContainerModel, and drives
the generic PageActionView (Show/Hide, OverrideImage/Text, etc.); the
action is hidden when the tab has no container.
