[Andorid] Migrate to ClipDrawable progress bar.

[Andorid] Migrate to ClipDrawable progress bar.

Using ClipDrawable progress bar helps future changes for
http://crbug.com/461148 as we only need pass to color parameters.

Also it has minor performance benefit.

Note: second landing attempt as the previous one made Chrome shell tests
      flaky. https://codereview.chromium.org/1170843002/
