Fixing regression in stack task clipping.
- Removing expensive calls to map coordinates of front task to the tasks
behind it, instead relying on the precalculated task rects that we
already compute on each stack change update. To prevent rounding
issues, the task rects are now float rects.
- Also fixing crash when RecentsActivity starts before the SystemUI
component (only an issue when pushing SysUI apks)
