Bug report

Bug description:

Found while working on #127946

This is sort of an extension to #127341, but not the exact same issue. If you define a setter before a getter, and then that getter has a docstring, a macro redefinition warning will occur, because the setter code sets the docstring to NULL.

Quick repro:

/*[clinic input]
@setter
Test.test
[clinic start generated code]*/

/*[clinic input]
@getter
Test.test

my silly docstring
[clinic start generated code]*/

The simplest fix is to just #undef the DOCSTR macro in the getter if it's been defined already. I have a PR at #127950.

CPython versions tested on:

CPython main branch
