Add ResTable_sparseTypeEntry support
Benchmarks on bullhead-userdebug show that there is a negligent
performance impact when using sparse entries on a 30% loaded
sparse type of 1000 resources.

New implementation of AssetManager/ResTable
The multiwindow model and Resources-per-activity
model that came in N puts greater demands on AssetManagers.
They are created whenever window dimensions change, which
can be frequently. There is a need to be able to cheaply
create a new AssetManager for each Activity, which shares
a lot of underlying state.
In order to make the creation of AssetManagers cheap,
we need a new implementation of the native AssetManager
and ResTable to support immutable representations of
APKs. This new data structure/class is ApkAssets.
ApkAssets have the same functionality of an AssetManager, except
that they operate on a single APK, and they do not do any caching.
Once loaded, they are immutable.
ApkAssets will be exposed as a Java object, with its implementation in
native code. The existing Java StringBlock will be owned by ApkAssets,
which means that Strings can be shared across AssetManagers.
ApkAssets can be cached by the ResourcesManager. Creating an AssetManager
requires only a list of ApkAssets and a configuration.
AssetManager2 (named with the suffix '2' for now while transitioning
to the new implementation) caches bags that are accessed.
Since ApkAssets are expected to be kept around longer, they do more validation
of the resource table, which cause slower load times. Measured on an angler-userdebug,
loading the framework assets takes 11ms with ApkAssets, and 2ms with the old
AssetManager implementation.
The tradeoff is that there does not need to be any security checks once an ApkAssets
is loaded, and regular resource retrieval is faster. Measured on an angler-userdebug,
accessing resource (android:string/ok) with many locales takes 18us with AssetManager2,
and 19us with AssetManager (this is per resource, so these add up).

Make tests use APKs instead of exploded APKs
Tests would expect parts of the APK to be unzipped and
maintained. Instead, we now decompress the required files
from the test APKs on test setup. This simplifies
test maintenance substantially.

Instead of hardcoding or assuming a path for testdata,
allow the testdata path to be specified via the command
line.

Introduce anydpi density resource qualifier
This is meant to be used with scaleable vector
drawables, and are chosen as the best match unless
there is a configuration that matches the density
requested exactly.

Support multiple resource tables with same package
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.

Move input library code to frameworks/native.
No longer compile libandroidfw as a static library on the device
since it already exists as a shared library. Keeping the static
library would force us to provide a static library version of
libinput for the device as well which doesn't make sense.
