Looks like we missed this, and so non-rooted locked devices can't override the persistent sysprops. On Pixel 8 for example, we ship with 'persist.arm64.memtag.system_server=off' by default (from some droidfood carry-overs), and this can't be edited (https://googleprojectzero.blogspot.com/2023/11/first-handset-with-mte-on-market.html).
We should allow these advanced users to set all the MTE properties on the device that they own, and they can already control the non-persistent properties.

Post OTA reboot, snapshot-merge threads will be run in the background cgroup so that they don't run on big cores. Hence, use SetTaskProfiles() API to move the thread to the relavant cgroup.
When setting SetTaskProfile API, /dev/cpuset/background/tasks path
is accessed which requires process to be in system group.
Use setgid to move the task to system group.

Use our standard macro for granting all the necessary permissions
instead of copying a part of it.
Add ioctl access for all clients for Unix stream sockets & pipes; this
allows them to be used for stdin/stdout without triggering
denials. (Only unpriv_sock_ioctls can be used.)
Together this allows a root shell to use `vm run` without getting
spurious denials such as:
avc: denied { ioctl } for comm="crosvm" path="socket:[835168]"
dev="sockfs" ino=835168 ioctlcmd=0x5401 scontext=u:r:crosvm:s0

Allow r_file_perms rather than just open+read, mainly because I saw
this denial:
avc: denied { getattr } for comm="binder:11247_2"

Also refactor slightly in microdroid_manager.te.

This prop is read in its .rc file to stop the service. Otherwise,
evertyime the service exits, it is restarted.
We don't want it to be `oneshot` because under normal operation, it
should be restarted if it exits/crashes.

Being a system_api_service prevents non-privileged apps from getting a reference to WearableSensingManager via Context#getSystemService (it returns null). CTS tests are run as non-privileged apps, so we need this change to properly test the API.
The API methods are protected by a signature|privileged permission. CTS tests can gain this permission by adopting the Shell's permission identity, but it can't get around the SELinux policy.
wearable_sensing_service is mostly modelled after ambient_context_service, which is an app_api_service, so we believe this change is fine from a security's perspective.
Test: A CTS test can get a WearableSensingManager via Context#getSystemService after this change.
