cgroup: Add CPUSetPartition= setting

Browse Source 
Add support for configuring cpuset partition type via the
CPUSetPartition= unit file setting. This controls the kernel's
cpuset.cpus.partition cgroup attribute.

The setting takes one of "member", "root", or "isolated". This is
useful for real-time workloads that require dedicated CPU resources
without interference from other processes.

When set, systemd will write the partition type to the
cpuset.cpus.partition cgroup file. If the kernel rejects the value
(e.g., due to partition hierarchy rules), a warning is logged and the
unit continues with the kernel's default partition type.
