/cache/overlay directory in support of overlayfs mounts on userdebug
and eng devices. Overlayfs in turn can be capable of supporting
adb remount for read-only or restricted-storage filesystems like
squashfs or right-sized (zero free space) system partitions
respectively.

Currently, both untrusted apps and priv-apps use the SELinux file label
"app_data_file" for files in their /data/data directory. This is
problematic, as we really want different rules for such files. For
example, we may want to allow untrusted apps to load executable code
from priv-app directories, but disallow untrusted apps from loading
executable code from their own home directories.
This change adds a new file type "privapp_data_file". For compatibility,
we adjust the policy to support access privapp_data_files almost
everywhere we were previously granting access to app_data_files
(adbd and run-as being exceptions). Additional future tightening is
possible here by removing some of these newly added rules.
This label will start getting used in a followup change to
system/sepolicy/private/seapp_contexts, similar to:
-user=_app isPrivApp=true domain=priv_app type=app_data_file levelFrom=user
+user=_app isPrivApp=true domain=priv_app type=privapp_data_file levelFrom=user
For now, this newly introduced label has no usage, so this change
is essentially a no-op.
Test: Factory reset and boot - no problems on fresh install.
Test: Upgrade to new version and test. No compatibility problems on
filesystem upgrade.

Steps taken to produce the mapping files:
1. Add prebuilts/api/28.0/[plat_pub_versioned.cil|vendor_sepolicy.cil]
from the /vendor/etc/selinux/[plat_pub_versioned.cil|vendor_sepolicy.cil]
files built on pi-dev with lunch target aosp_arm64-eng
2. Add new file private/compat/28.0/28.0.cil by doing the following:
- copy /system/etc/selinux/mapping/28.0.cil from pi-dev aosp_arm64-eng
device to private/compat/28.0/28.0.cil
- remove all attribute declaration statement (typeattribute ...) and
sort lines alphabetically
- some selinux types were added/renamed/deleted w.r.t 28 sepolicy.
Find all such types using treble_sepolicy_tests_28.0 test.
- for all these types figure out where to map them by looking at
27.0.[ignore.]cil files and add approprite entries to 28.0.[ignore.]cil.
This change also enables treble_sepolicy_tests_28.0 and install 28.0.cil
mapping onto the device.
