[!71] Make TreePath<i...> an alias for HybridTreePath<index_constant<i>...>
Merge branch 'feature/merge-treepath-classes' into 'master'
ref:staging/dune-typetree> This removed the explicit implementation of TreePath<i...> and makes it an alias for HybridTreePath<index_constant...>. While it is intended that TreePath is completely removed, there might be incompatibility issues if downstream modules switch to HybridTreePath but their users still use TreePath. Such issues should be avoided by this patch.
