[chore] Add cgroupruntime extension integration tests (#39017)

<!--Ex. Fixing a bug - Describe the bug and how this fixes the issue.
Ex. Adding a feature - Explain what this achieves.-->
#### Description

Reverts
#37224
with a few additional changes:

- Decouple `sudo` integration tests from non-privileged ones from the
makefile. -> **prevent sudo promp when running integration tests**
- Adds a specific `intengration-sudo-tests` check in the CI that only
targets the cgroupruntime extension as being the only component that
currently requires this setup.
- Sets darwin and windows as unsupported platforms (it requires cgroup
file system).

<!-- Issue number (e.g. #1234) or full URL to issue, if applicable. -->
