[chore] Add cgroupruntime extension integration tests

[rogercoll]

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).

Looks like the integration test is flaky: Error: Process completed with exit code 143. https://github.com/open-telemetry/opentelemetry-collector-contrib/actions/runs/14124954048/job/39571961728?pr=39017

My guess is that the tests modifies the cpu and memory limits and as GitHub-hosted runners have strict resource limits it kills the process/test. Checking if we could reduce the resource changes limits.

Memory usage of the tests:

The integration tests were setting the cgroup max memory to the 10% of 128 Mb, thus in some runs triggering the OOM killer -> 134 exit code.

Increasing the cgroup max memory setting from 128Mb to 4GB (should not be an issue if the system has less total memory) seems to fix the issue.
