Named objects (FileMapping, Mutex, Semaphore) should be opened with ALL_APPLICATION_PACKAGES SID

[bradgrantham-lunarg]

UWP (AppContainer ) apps cannot open named resources without explicit granted permission. The API Layer uses named file mappings, mutexes, and semaphores, and those will need to be opened with ALL_APPLICATION_PACKAGES permission. It's not clear that those can be created from within UWP with that permission, so we may need to rearchitect with a service outside UWP that creates or brokers those objects.
