Gestures are missing

[lytico]

Although Gestures are somehow defined,
it seems that they are never registered:

https://github.com/Redth/Maui.Gtk/blob/main/src/Platform.Maui.Linux.Gtk4/Platform/GtkGestureExtensions.cs

Missing is something like

https://github.com/dotnet/maui/tree/main/src/Controls/src/Core/Platform/GestureManager

[lytico]

seems there is an issue to resolve this: dotnet/maui#12947
