This PR adds support for the raw_exec driver on systems with only cgroups v2. The raw exec driver is able to use cgroups to manage processes. This happens only on Linux, when exec_driver is enabled, and the no_cgroups option is not set. The driver uses the freezer controller to freeze processes of a task, issue a sigkill, then unfreeze. Previously the implementation assumed cgroups v1, and now it also supports cgroups v2. There is a bit of refactoring in this PR, but the fundamental design remains the same. Closes #12351 #12348
