[TreeView] Remove deprecated TreeView component

[flaviendelangle]

Closes #14768

Changelog

Tree View

• The <TreeView /> component has been renamed <SimpleTreeView /> which has exactly the same API:

  -import { TreeView } from '@mui/x-tree-view';
  +import { SimpleTreeView } from '@mui/x-tree-view';
  
  -import { TreeView } from '@mui/x-tree-view/TreeView';
  +import { SimpleTreeView } from '@mui/x-tree-view/SimpleTreeView';
  
     return (
  -    <TreeView>
  +    <SimpleTreeView>
         <TreeItem itemId="1" label="First item" />
  -    </TreeView>
  +    </SimpleTreeView>
     );

  If you were using theme augmentation, you will also need to migrate it:

   const theme = createTheme({
     components: {
  -    MuiTreeView: {
  +    MuiSimpleTreeView: {
         styleOverrides: {
           root: {
             opacity: 0.5,
           },
         },
       },
     },
   });

  If you were using the treeViewClasses object, you can replace it with the new simpleTreeViewClasses object:

   import { treeViewClasses } from '@mui/x-tree-view/TreeView';
   import { simpleTreeViewClasses } from '@mui/x-tree-view/SimpleTreeView';
  
  -const rootClass = treeViewClasses.root;
  +const rootClass = simpleTreeViewClasses.root;
