Support both grid and large tile with gridOnlyOverivew

- With the introduction of Desktop windowing, we'll need to supprot grid task and large tile (desktop tile) coexisting
- The previous gridOnlyOverview aimed to have taskSize matches actual grid task size, and introduced another carouselTaskSize for scaling in swipe up carousel
- Now I'm reverting to pre-gridOnlyOverview implementation of having taskSize as both large tile size and carousel task size, and gridTaskSize as only task size in grid

TaskViewSimualtor
- Removed no longer needed carousel translation and related calculations
- mIsGridTask is now determined with DeviceProfile, so when swipeing to Desktop task it won't use grid task size

TaskView
- Removed no longer used nonGridPivotTranslationX

RecentsView
- Make getSelectedTaskBounds / getTaskBounds picks the correct taskSize
