Remove GVFS.Service.UI (dead code)

The Service.UI process displayed Windows toast notifications, but only
the MountFailure notification was actively sent, and it provided no
useful value. Removing eliminates XmlSerializer and WinRT COM interop
dependencies that would block NativeAOT compilation.

Removes: project, unit tests, installer integration, service launch
logic, notification handler, diagnostics log collection, and the
Microsoft.Windows.SDK.Contracts package.
