Sangwoo Ko b7a3eeb712 [Tree Tabs] Add split tab support for tree tabs (#34659 )

* Add split tab support for tree tabs

In order to support split tabs in tree tabs, mainly we need to reimplment
two methods - CreateSplit and Unsplit.

For CreateSplit, we need to wrap the split tabs in a tree node, and insert it
at the position.
For Unsplit, we need to extract the tabs back to the tree nodes.

- TabStripCollection: virtual CreateSplit, Unsplit, AddCollectionMapping,
  RemoveCollectionMapping; AddTabCollectionAtPosition for delegate.

- BraveTabStripCollection(delegate): override CreateSplit/Unsplit and
  AddCollectionMapping/RemoveCollectionMapping; PassKey overloads for
  AddTabCollectionAtPosition and collection mapping.

- BraveTreeTabStripCollectionDelegate: implement CreateSplit (wrap split in
  tree node, insert at position), Unsplit (extract tabs back to tree nodes),
  AddCollectionMapping/RemoveCollectionMapping for TREE_NODE holding split/group;
  MoveTabsRecursive same-position handling for split/group creation.

- Tab strip API: handle TREE_NODE in tab_converters (unpinned container).

- Docs: tree tabs + split tabs flow and MoveTabsRecursive behavior.
