[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'
