Remove deprecated function `locale.getdefaultlocale`

[picnixz]

Feature or enhancement

It was deprecated in Python 3.11, and planned to be removed in 3.13, but then delayed until 3.15.

Some related issues that we maybe need to solve before really removing it: #130796.

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere

@picnixz it seems to be a good issue for first-time contribution. Could I help with it?

This one has to wait.

I created a draft for when the dependent is resolved. What do we want to do with windows_locale? It is now no longer used, and is not documented, but also not private for some reason. Deprecate normally for 3.16 or similar depending on external usage?
