[Fuzz] Add Fuzz testing for FancyZones (#38165)

* Add FancyZones.FuzzTests Module for fuzzing grid from json element * remove unuse test cs * fix spell error * remove specific modify in job-fuzz.yml * add Testably.Abstractions.FileSystem.Interface.dll * fix spell error * add dependency dll * add annotations * fix pipeline error need to import 'Common.Dotnet.CsWinRT.props'
