gh-112087: Make list_{slice, ass_slice, subscript} to be threadsafe

[corona10]

• Issue: Make list objects thread-safe in --disable-gil builds #112087

[corona10]

test_list_getslice (test.test_capi.test_list.CAPITest.test_list_getslice) ... Fatal Python error: Segmentation fault

hmm I will take a look, it actually callis PyList_GetSlice()

[corona10]

Okay, I found my mistake.. let me fix.

[corona10]

@colesbury Ready to be reviewed :)

[colesbury]

LGTM, but I think it might be worth adding the x = []; x[:] = x test case to list_tests.py

[corona10]

LGTM, but I think it might be worth adding the x = []; x[:] = x test case to list_tests.py

Ah, I missed it

⚠️⚠️⚠️ Buildbot failure ⚠️⚠️⚠️

Hi! The buildbot AMD64 Debian PGO 3.x has failed when building commit 6cddc73.

What do you need to do:

1. Don't panic.
2. Check the buildbot page in the devguide if you don't know what the buildbots are or how they work.
3. Go to the page of the buildbot that failed (https://buildbot.python.org/all/#builders/249/builds/7937) and take a look at the build logs.
4. Check if the failure is related to this commit (6cddc73) or if it is a false positive.
5. If the failure is related to this commit, please, reflect that on the issue and make a new Pull Request with a fix.

You can take a look at the buildbot page here:

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.
If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:
git switch -c <new-branch-name>
Or undo this operation with:
git switch -
