Refactor output cache checks for edit/preview mode

- Added necessary using directives in `KenticoFeatureExtensions.cs` for new implementations.
- Created `XperienceCommunity.OutputCache.Extensions` namespace with `KenticoFeatureExtensions` class, introducing `InPreview` and `InEditMode` methods to extend `HttpContext`.
- Removed unused `Kentico.Web.Mvc` and added `XperienceCommunity.OutputCache.Extensions` using directive in `XperienceOutputCachePolicy.cs`.
- Refactored `XperienceOutputCachePolicy` to use new extension methods for preview/edit mode checks, enhancing readability.
- Fixed formatting in `XperienceCommunity.OutputCache.csproj` for `PackageReference`.
