[Linux] Merge UI And Platform thread (#162671 )

Disabled by default, to enable use
`fl_dart_project_get_ui_thread_policy`:
```cpp
  g_autoptr(FlDartProject) project = fl_dart_project_new();
  fl_dart_project_set_ui_thread_policy(project, FL_UI_THREAD_POLICY_RUN_ON_PLATFORM_THREAD);
```

With this PR, the UI isolate now runs on platform thread, which allows
for synchronous calls to Gtk, as well as synchronous calls from Gtk to
Flutter. For example something like this is now possible:

```dart
typedef GtkWindow = Pointer<Void>;

void setWindowPosition() {
  final library = DynamicLibrary.executable();
  // Hypothetical function to get pointer to GtkWindow
  final getMainWindow = library
      .lookupFunction<GtkWindow Function(), GtkWindow Function()>(
        'get_main_window',
      );
  final gtkWindowResize = library.lookupFunction<
    Void Function(GtkWindow, Int32, Int32),
    void Function(GtkWindow, int, int)
  >('gtk_window_resize');
  final window = getMainWindow();
  gtkWindowResize(window, 200, 200);
}
```
