high contrast themes: ListTile selected state is not distinguishable from non-selected state

[d-loose]

For the high contrast themes the primaryColor defaults to either black or white, so that selected ListTiles are visually indistinguishable from non-selected ones.

	Light	Dark
Normal
High Contrast

Minimal example:

import 'package:flutter/material.dart';
import 'package:yaru/yaru.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return YaruTheme(
      builder: (context, yaru, child) {
        return MaterialApp(
          theme: yaru.theme,
          darkTheme: yaru.darkTheme,
          highContrastTheme: yaruHighContrastLight,
          highContrastDarkTheme: yaruHighContrastDark,
          title: 'Flutter Demo',
          home: Scaffold(
            body: ListView(
              children: const [
                ListTile(
                  selected: true,
                  title: Text('selected tile'),
                ),
                ListTile(
                  selected: false,
                  title: Text('unselected tile'),
                )
              ],
            ),
          ),
        );
      },
    );
  }
}

        );
      },
    );
  }
}

the listtile theme was somehow traited without much attention because we used a lot of those master tiles
will work on this in the eve
