cgroup: replace cgroup_subsys->disabled tests with cgroup_subsys_enabled()
Replace cgroup_subsys->disabled tests in controllers with cgroup_subsys_enabled(). cgroup_subsys_enabled() requires literal subsys name as its parameter and thus can't be used for cgroup core which iterates through controllers. For cgroup core, introduce and use cgroup_ssid_enabled() which uses slower static_key_enabled() test and can be indexed by subsys ID. This leaves cgroup_subsys->disabled unused. Removed.
