Static RRO package is designed to support resource overlay for system
server and they shouldn't be disabled or changed by a user.
The design details are in go/treble-static-rro.
Selection method for static RROs will be applied later when its design
is determined.
Test: building succeeded and tested on sailfish.

Hand over ownership of overlays to OverlayManagerService.
Changes to a package's overlays are propagated using the activity life
cycle. Affected activities will be recreated as needed. This provides a
well-defined point to modify an application's assets while the
application is paused.
Consolidate how overlays targeting the system and overlays targeting
regular applications are handled. Previously, system overlays were
handled as a special case. Now, everything is handled identically. As a
side effect, the call to idmap --scan during Zygote boot has become
obsolete and is removed.
Information on what overlays to use is recorded in
ApplicationInfo.resourceDirs. The PackageManagerService is responsible
for the creation of ApplicationInfo objects. The OverlayManagerService
is responsible for informing the PackageManagerService in advance about
what resourceDirs to use.
When launching an application, the ApplicationInfo is already populated
with up-to-date information about overlays.
When enabling or disabling an overlay for a running application, the
OverlayManagerService first notifies the PackageManagerService about the
updated resourceDirs. It then tells the ActivityManagerService to push
the new ApplicationInfo object to the application's ActivityThread.
Finally the application requests its ResourcesManager to create new
ResourcesImpl objects based on the updated paths.

The 'idmap --scan' command was limited to only scan a single directory
for overlay packages. Update idmap to support any number of directories.

In order to support APK split features, the resource
table needs to support loading multiple resource
tables with the same package but potentially new set
of type IDs.
This adds some complexity as the type ID space changes
from dense and ordered to potentially sparse.
A ByteBucketArray is used to store the type IDs in
a memory efficient way that allows for fast retrieval.
In addition, the IDMAP format has changed. We no longer
need random access to the type data, since we store the
types differently. However, random access to entries of
a given type is still required.
