Some CI updates

• Windows 2019 has reached its mainstream EoL on Jan 9, 2024, with extended support until Jan 9, 2029. Should we consider drop 2019 and Win8 compat?
• Windows 2025 is out. Consider adding it to CI.
• ubuntu-24.04-arm is out. Consider adding more native arm tests. Currently, it is used only in GWP-Asan tests.
• ubuntu-20.04 will reach its EoL in two months and its packages begin to cause troubles in some PRs. Should we consider drop it and migrate to ubuntu-24.04?

Found that ubuntu-20.04 still has pro support and legacy support:

• https://ubuntu.com/about/release-cycle
• https://learn.microsoft.com/en-us/lifecycle/products/windows-server-2019

I personally discourage maintaining such support in the upstream. Since such support is pro, if Canonical finds their subscribers in need of certain upstream updates, then it should be their duty to backport the changes. Similar argument applies to Windows' extended support in my understanding. My interpretation may be too strong though 😄

Thanks for thinking about this. I think we should if support for 20.04, Win8 and 2019 gets in the way, then I think we can drop them from CI. I don't want to drop unless we have a reason though. I think adding 24.04-arm, would be great. I have some CI changes, so I'll take a pass at this.
