If for some reason the resource id cannot be resolved to a value
(there is no configuration that matches the AssetManager configuration
or some error occurs), set the resource id of the SelectedValue to the
resource id that could not be resolved. This was the behavior before
the AssetManager IncFs hardening refactor.

When calling Resources#obtainStyledAttributes, if a value for an
attribute is supplied from the theme, and the value in the theme
is a reference to a resource, the reference will be resolved using
AssetManager2::ResolveReference each time the value from the theme
is selected. This causes Resources#obtainStyledAttributes to do
repeated work every time the same attribute is supplied from the
theme in multiple invocations.
Caching the result of ResolveReference reduces the cost of this
repeated work and reduces the amount of time needed to inflate views.

In ag/5859897 we started tracking source styles for each TypedValue.
It is also useful to keep track of source layouts if the attribute
was resolved against a layout (attribute set in XML layout inside
of <View> tag).

This API will be used by Android Studio layout inspector to
query where a given resource attribute originated from to allow
developers to have an easier way to find what needs to be changed
to affect a given resource attribute.

The out parameter `out_indices` is expected to be non-null
and so the extra null check adds a cost to performance
and opens the door to misusing the API by not supplying
`out_indices`.

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.

Mark input uint32_t[] as const. Use Read-only JNI
array access for input as it's faster than critical access.
Use non-movable arrays for TypedArray so that the address can
be resolved and stored, avoiding the need to do JNI array
access for the output.
Indicies is always non-null, so remove the optional checks.
Eliminate unused return value.

Without the entire JNI environment, testing the attribute
resolution code will be much easier and enable safer
refactoring.
