OverlayResourceProvider class Null safety

A resource provider that allows clients to overlay the file system provided by a base resource provider. These overlays allow both the contents and modification stamps of files to be different than what the base resource provider would report.

This provider does not report watch events when overlays are added, modified or removed.
