To make S finalization easier, this changes the framework SDK so that
apps linking against it will be able to continue working as expected
after the first phase of SDK finalization.
During the first phase of SDK finalization, the resource ids of
resources that have not been removed are finalized.
staging-public-group tags are converted to staging-public-group-final
tags in order to encode into the framework what the staged resource id
of a finalized resource was. When an app recompiles, it will use the
finalized resource id. Then after all apps recompile, phase 2 of
finalization begins, in which the staging-public-group-final tags are
removed so apps can no longer use the staged resource ids.
Apps that link against the SDK (provided they are using a recent
version of aapt) will encode references to staged resources as
TYPE_DYNAMIC_REFERENCE and TYPE_DYNAMIC_ATTRIBUTE. The values of R
fields for staged resources are defined out-of-line to prevent them
from being inlined into apps linking agsint the SDK. This allows the
resource ids to change during phase 1 of API finalization.

staging-public-group is a tag for putting resources that have been
added during platform development, but have not yet been finalized,
into a separate resource id namespace.
R.java fields of staged resources are non-final, so when the SDK is
finalized, applications using the android R.java will automatically
use the new finalized resource id without having to recompile.
Staged resources can exist either in the same type id as the type's
non-staged counterpart or in a separate type id. Multiple
staging-public-group tags each with a different type id can exist
simultaneously, which allows for multiple versions of the platform
to be developed at once.

This changes refactors tests to use the NewResourceBuilder class
that makes it easier to construct resource entries.

If a shared library exposes an attribute and a client uses the
attribute in its own styleable, the value of the lib attribute
resource id in the client styleable must be fixed with the correct
package id at runtime. Since the client will not have an
onResourcesLoaded to call, the client should directly reference the
attribute resource field in its styleable.

Add uses-split dependencies to AppInfo. At link time, this is used
and allows features to reference other features, before
resource namespacing is implemented in Android Studio.

For normal app development, the desired linking semantics are:
* styleables - take union of all definitions
* all other resources - take last non-weak definition
This differs from the semantics needed in other scenarios, where
merging/overlaying styles is desired.

There exists a discrepancy between how aapt1 and aapt2 prevent the
compression of assets using the -0 flag. aapt1 checked if the file name
ended with an argument, but aapt2 is checking if the file extension
exactly matches the argument. This change makes aapt2 behave the same as
aapt1 for asset compression using the -0 flag.

To try and solve test flakiness, hold the unique_ptr in the method scope to make sure it's cleaned up after we assert on it.

Raw attribute values are not included in xml files when building binary
APKs but they are when building proto APKs. Remove raw attribute values
and create a new convert flag that (--keep-raw-values) that allows raw
value to be kept.
Also added flag to link to keep raw attribute values.
