Improve non-native completion in Python mode

Browse source 
Previously, both the definition of __PYTHON_EL_get_completions
and the call to __PYTHON_EL_get_completions were sent to the
inferior Python each time
'python-shell-completion-get-completions' was executed.
However, there is no need to send the definition every time as
long as the definition remains unchanged.  We improved this so
that the definition of __PYTHON_EL_get_completions is only sent
during the inferior Python initialization; it is no longer sent
during 'python-shell-completion-get-completions' execution.
* lisp/progmodes/python.el
(python-shell-completion-send-setup-code): New function.
(python-shell-first-prompt-hook): Add the above new function.
(python-shell-completion-get-completions): Omit sending
'python-shell-completion-setup-code'.  (Bug#80182)
