Some functionality based on eBPF attached to tracepoints (gpu memory
accounting and time-in-state) rely on newer devices running with
"disabled" perf_event_paranoid controls as a result of the kernel having
LSM hooks in the perf_event_open syscall instead. This is tested
for, and set up by init via the sys.init.perf_lsm_hooks sysprop.
Development devices that boot into permissive mode still want the
eBPF-based functionality to work, but end up with a paranoid value that
disallows the syscall, as the LSM hook test expects to observe a SELinux
denial (which doesn't happen due to permissiveness).
As a pragmatic way of achieving the paranoid value override, we pretend
that the hook test has succeeded if we detect permissive SELinux during
second-stage init. It'd be nicer if we had a sysprop to reflect the
device's on-boot status of SELinux, but it's not worth adding for this
case.

Bug: 170674916
Tested: booted crosshatch-userdebug with permissive kernel cmdline,
confirmed that the log message from the new codepath was present
in logcat, sysprop is 1, and paranoid is -1.

For devices using utilclamp create cpu controller hierarchy. Do not
remove schedtune hierarchy yet because init.rc is generic and should
work with devices which still use schedtune.

The critical services can now using the interface `critical
[window=<fatal crash window mins>] [target=<fatal reboot target>]` to
setup the timing window that when there are more than 4 crashes in it,
the init will regard it as a fatal system error and reboot the system.
Config `window=${zygote.critical_window.minute:-off}' and
`target=zygote-fatal' for all system-server services, so platform that
configures ro.boot.zygote_critical_window can escape the system-server
crash-loop via init fatal handler.
