Miss Islington (bot) 2a3189ce67 [3.15] gh-80937: Fix memory leak in tkinter createcommand (GH-152294) (GH-152327)

A command created with createcommand() held a strong reference to the
interpreter, forming an uncollectable cycle (interpreter -> command ->
interpreter) that kept the interpreter and the callback alive until the
command was removed with deletecommand() or destroy().  The command now
borrows the reference; it cannot outlive the interpreter, which deletes its
commands when finalized.
(cherry picked from commit bbf7786a90)
