(python-base-mode-map): Use it!

Rather than use `copy-keymap` between `python-mode-map` and
`python-ts-mode-map`, move the shared bindings to `python-base-mode-map`.

* lisp/progmodes/python.el (python-base-mode-map): Define it explicitly.
Move all the bindings of `python-mode-map` to it.
(python-mode-map, python-ts-mode-map): Inherit from it.
