Update corner radius calculation in TaskView

TaskThumbnailView
- Set cornerRadius directly from TaskView instead of calulating and listening from ViewModel
- Use onSizeChagned/width/height for OutlineProvider bounds, to be consistent with DesktopTaskContentView

DesktopTaskView
- Moved backgroundView inside DesktopTaskContentView, so its outline can be determiend by OutlineProvider in DesktopTaskContentView
- Update DesktopTaskContentView's cornerRadius when it changes in TaskView

Model/Data chagnes
- Removed TaskViewModel/TaskViewData and scale from RecentsViewData

TaskView
- Add a onBind method to be called after bind, for common post bind handling (e.g. update cornerRadius)

TaskViewSimualtor
- Use DesktopFullscreenDrawParams for desktop task, and moved setIsDesktopTask to CTOR so related fields can be final
