csharp: skip static members from interfaces

Summary:
Static methods of eo-interface are generated in c# interface-concrete. there are
4 methods
`efl_access_object_access_root_get`, `efl_access_object_event_emit`,
`efl_access_object_event_handler_add`, `efl_access_object_event_handler_del`

If a class that inherits that interface, static method can't be called via
classname.

This commit changes eolian_mono by removing those static members from the C#
interface-concretes. If a generated class implements the interface, the static
member is generated as static member of the class directly.

Depends on D9800

Test Plan: Check that `Efl.Ui.Widget` has `public static Efl.Object AccessRoot` property.
