BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=1875 1. Separate the AutoGen.py into 3 small py files. One is for AutoGen base class, one is for WorkspaceAutoGen class and PlatformAutoGen class, and the one for ModuleAutoGen class. 2. Create a new class DataPipe to store the Platform scope settings. Create a new class PlatformInfo to provide the same interface as PlatformAutoGen. PlatformInfo class is initialized by DataPipe instance. Create a new class WorkspaceInfo to provide the same interface as WorkspaceAutoGen. WorkspaceInfo class is initialized by DataPipe instance. 3. Change ModuleAutoGen to depends on DataPipe, PlatformInfo and WorkspaceInfo. Remove the dependency of ModuleAutoGen to PlatformAutoGen.
