Refactor LZMA generation to support Docker and Antares usage

List explicitly as .csproj files the scenarios for which the offline package cache is important

Produces new artifacts designed for various scenarios, such as:
 * Docker (where xml doc files are not needed)
 * Azure web apps (where 1.x SDKs must still be supported, but xml docs are not needed)
