Correct bad imports in optimize.py and expose it via `pytensor.tensor.__init__` (#1464)

* Expose `pt.optimize` * Clean up imports in optimize.py * Add example notebook for `optimize.root` * Small updates * Add doc file * Link to optimize docs in tensor index * Add docs to user-facing functions. * Move `scipy.optimize` imports into `perform` methods * Use global import strategy * Remove props and overload __str__ * rerun example notebook
