system server reads this property to keep track of whether server
configurable flags have been reset during current boot.
system server needs this information to decide whether to perform
following disaster recovery actions on framework level.

the get_prop added in this cl in system_server.te is not grouped
in the same place as the set_prop in system_server.te in another
cl (https://android-review.googlesource.com/c/platform/system/sepolicy/+/828284).
This is because these 2 properties are serving for different purposes:
device_config_flags_health_check_prop is used to control features(so will be
all the future set_prop added by other feature teams under "# server configurable flags properties"),
while device_config_reset_performed_prop is used by our API's internal implementation.
So I feel like it might be clearer if I put this get_prop in a different place rather than
appending to "# server configurable flags properties".

Test: build suceeded.

I added ro.bionic.(2nd_)?_(arch|cpu_variant) to vendor system
properties. And have init to write them to files under dev/.

This change set SELinux rules for these properties and files.

For the system properties: vendor/default.prop will set them. init will
read them.
For the files /dev/cpu_variant:.*: init will write them. bionic libc
will read them. (Basically world readable).

This is to allow libc select the right optimized routine at runtime.
Like memcpy / strcmp etc.

Test: getprop to make sure the properties are set.
Test: ls -laZ to make sure /dev/cpu_variant:.* are correctly labeled.

The dynamic linker calls realpath(3) on paths found in the linker config
script. Since realpath() calls lstat() on the parent paths, not allowing
getattr on /apex and its subdirectories will cause selinux denial spam
whenever something is executed from APEXes.

Silence the spam by allowing getattr on apex_mnt_dir.

device_config_flags_health_check_prop is used for enabling/disabling
program flags_health_check which is executed during device booting.
"1" means enabling health check actions in flags_health_check, other
values mean flags_health_check will not perform any action.

With Treble, cameraserver no longer depends on camera devices directly.
Moreover, pixel 3 doesn't have /dev/cam node.

We still keep "camera_device" type around since vendor policy uses it to
label its /dev nodes.

1b1d133b added the process2 class but
forgot to suppress SELinux denials associated with these permissions
for the su domain. Suppress them.

Ensure xdp_socket is in socket_class_set, so the existing dontaudit rule
in su.te is relevant. Inspired by
https://github.com/SELinuxProject/refpolicy/commit/66a337eec6d7244e44e51936835b4e904f275a02

It is unnecessary to use get_prop() rules for the su domain. The
su domain is always in permissive mode [1] and not subject to SELinux
enforcement. It's also possible these rules were added to avoid SELinux
denial log spam from showing up, however, there are already dontaudit
rules in place [2] to prevent this.

Delete the unnecessary rules.
