Add support for AssemblyStore v3

[jamescrosswell]

Description

net9.0-android and net10.0-android use slightly different versions of the AssemblyStore format to bundle all of the assemblies required to run an app on Android into an AAB.

Changes for v3

The changes for version 3 are thankfully pretty minor, but we do have to account for them. A field has been added to allow ignoring some assemblies without including them in the store (https://github.com/dotnet/android/blob/main/Documentation/project-docs/AssemblyStores.md#index).

This field will only be present in Assembly stores with a FORMAT_VERSION of 3+ in the header.
