Frontend.XF.*: fix references in .fsproj files

[webwarrior-ws]

Fix project references in Fronend.XF.*.fsproj files by adding <Project> element with project guid to each project reference. This is needed to avoid "error : Unrecognized Guid format" error when loading projects in Visual Studio 2022.

@webwarrior-ws wrong scope in commit msg title; you wrote Frontend.XF, but you're not changing that project or any file inside the Frontend.XF folder. I guess you meant Frontend.XF.*.

Do you still get this error if this PR is not merged?
