Compositor: remove scene.node_tree from Python API

Browse Source 
Since we are removing `scene.use_nodes` in #143578, most developers
will have to update their python script by replacing `scene.node_tree`
by `scene.compositing_node_group` in order to create a new compositing
 node tree anyways. So we remove `scene.node_tree`.

Note: `scene->nodetree` in `scene_blend_write()` is still being written
to the blend file, so forward compatibility is not affected by this PR.
