CI,scripts,snap,Frontend.Maui: use .NET 8

Switch to using .NET 8 for all frontends. Use Maui 8 on Gtk.
This unifies .NET versions and gets rid of .NET 6, which is
nearing end of suport anyway.

Update Microsoft.Extensions.DependencyInjection to v 8.0.0.
This iss needed to avoid error:
```
error NU1605: Warning As Error: Detected package downgrade:
Microsoft.Extensions.DependencyInjection from 8.0.0 to 6.0.0. Reference
the package directly from the project to select a different version.
```

Install maui workloads on windows--dotnet8-* lanes so that
Maui/Android can be built.

Call fsxc with DOTNET_ROLL_FORWARD=Major to allow it to run
under newer .NET version (we use .NET8 now, and fsxc is
compiled for .NET6).
