Description
This PR adds memory management parameters to the Linux test execution pipeline to prevent out-of-memory (OOM) failures on Ubuntu 24.04 test agents. The changes implement specific garbage collection and parallelism restrictions to reduce memory consumption during test runs.
These changes are implemented to mitigate ADO agents from killing the process and causing Linux test step to be flaky.
