[Resolve] Introduce an ability to get all moduleInfos without filtering by platform

Previously, each ProjectResolutionFacade was tied to the respective
platform, so there were no point in collection moduleInfos for all
possible platforms.

For composite resolution mode, we have to get all modules no matter
what their platform is (because all modules will be analyzed in one
facade), so this commit adds such an ability.
