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.

@colesbury Ready to be reviewed :)

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

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:
