Add experimental CI for CPython 3.13

[corona10]

• Add CPython 3.13 as the experimental CI
• Upgrade greenlet to 3.0.0-rc3
• Update CPython 3.12 as the non-experimental CI
• Remove Python 3.7 from the CI (EOL)
• Set 3.12 default CPython version for other platforms

The CI is failing for 3.12 on macOS and Windows, does this need fixing?

Also PyPy3.8 on Ubuntu is failing, but this could be removed because it's no longer supported:

Okay!

Hmm in my local environment macOS
It passed!

@hugovk Let's separate the PR to fix the Windows and macOS GA runner issue.

Windows was already broken from 3.10
#317

We should handle the directory issue on GA but as I commented let's create an issue and solve it separately.

In macOS, /var is a symlink to /private/var.

Yeah, it's looks complex issue than I expected, let's solve it separately cc @hugovk
