Account for children margins when orienting popup container.

Instead of recalculating the orientation after adding margins,
we account for the margins in the initial calls to orientAboutObject.

This ensures consistent mIsAboveIcon throughout calls to show the popup.

- Also updates the smaller radius to match the middle items.

Bug: 175329686
Test: long press on item where height and height without margins would
      result in differing mIsAboveIcon values
      eg. the 3rd item in a folder in the top middle of 5x5 workspace
