[views-ax] Migrate kName in TabGroupHeader

This CL migrates the kName attribute in views to be updated
whenever its value should change, rather than querying the value
and computing it only when needed.

The accessible name of a TabGroupHeader depends on the following properties:

1. The title of the TabGroup
2. The collapsed state of the TabGroup
3. The content string of the TabGroup, which is influenced by the title of the first tab and the number of tabs in the group.

Since the accessible name of the TabGroupHeader depends on the title of the
first tab in the group, we track Tab::SetData() whenever it attempts to
update the tab’s title. If an update occurs,
TabGroupHeader::UpdateAccessibleName() is called.

Additionally, whenever a tab is added to or removed from a TabGroup, the
accessible name of the TabGroupHeader must be recalculated. To achieve
this, we need to add a callback in the TabGroup class and execute it
whenever a tab is added or removed.

The tab’s title update request is initially handled in WebContents,
and then a subsequent UI update is scheduled for the browser to handle.
The title update is performed through a delayed task to avoid flickering.

This CL is part of the ViewsAX project:
