add ModuleInfo collection to IModuleManager

[dansiegel]

Description of Change

Prism previously introduced a number of great extensions off of the IModuleCatalog to check if a Module exists, or is initialized, however in order to validate the current state of a module you must inject both the IModuleManager and IModuleCatalog.

In this scenario it is extremely unlikely that you care at all about the IModuleCatalog and that you only want to be able to load an uninitialized Module. These changes simplify the dependencies you need to handle this simple task.
