(cherry picked from commit 9fbd6520)

Files in /proc/net leak information. This change is the first step in
determining which files apps may use, whitelisting benign access, and
otherwise removing access while providing safe alternative APIs.

To that end, this change:
* Introduces the proc_net_type attribute which will assigned to any
new SELinux types in /proc/net to avoid removing access to privileged
processes. These processes may be evaluated later, but are lower
priority than apps.
* Labels /proc/net/{tcp,tcp6,udp,udp6} as proc_net_vpn due to existing
use by VPN apps. This may be replaced by an alternative API.
* Audits all other proc/net access for apps.
* Audits proc/net access for other processes which are currently
granted broad read access to /proc/net but should not be including
storaged, zygote, clatd, logd, preopt2cachename and vold.

This is a partial cherry pick of commit 6231b4d9
'Enforce per-app data protections for targetSdk 28+'.

Untrusted_app_27 remains unreachable, but it's existence
prevents future merge conflicts.

Restrictions introduced in vendor init mean that new devices
may not no longer exempt vendor init from writing to system_data_file.
This means we must introduce a new label for /data/vendor which
vendor_init may write to.
