cc: Delete resources when ResourceProvider shuts down.

When the ResourceProvider is destroyed, it should destroy the
resources it owns, and notify the creators of the resources that
they are released (in the TextureMailbox case).

If the context is lost, then callback should inform the creator
that the resource is destroyed in the callback. So a bool is
added to make this information known.

If a resource is in use in the parent, it will be leaked still, which
is a known issue and will be addressed in the future.

Tests:
ResourceProviderTest.Shutdown
ResourceProviderTest.LostContext
ResourceProviderTest.ShutdownWithExportedResource
