1. Enable treemap emphasis label formatter. Fix #11854. And add test cases.
[Details]:
The implementation of "insert levelModel" is migrate from "Tree.getModel"
to "beforeLink nodeData.wrapMethod('getItemModel', ...)", because the former
one miss the case of `data.getItemModel`, which is needed in label formatter
fetcher.
2. Fix the incorrect implementation of `leavesModel` in `TreeSeries`.
This defect is found when fix "1". "1" and "2" are sharing the same data
structure (Tree, insert model) so we'd better fix them together.
[Details]:
`leavesModel` should be inserted between the node `itemModel` and the
`seriesModel` in the "parentModel" chain.
It can be added either via [A] "beforeLink -
nodeData.wrapMethod('getItemModel, ...)"
or via [B] "TreeNode.getModel ".
But `TreeSeres` both use the two strategy, which causes the `leavesModel` is
inserted twice.
