It seems that this PR had a problem.
It provides incorrect clearing of generator frame locals without checking any another references on this frame.
In this PR we can see a more accurate way of clearing such a frame.

Sorry, @efimov-mikhail and @sobolevn, I could not cleanly backport this to 3.13 due to a conflict.
Please backport using cherry_picker on command line.
