Fix omnibox popup suggestions on rotation on iOS 11.

It seems like on iOS 11 the autoresize masks don't work well when the
device is rotated. Since suggestions rows don't really need the mask
since the frame of each view is exactly calculated and set every time it
changes the size, remove the use of autoresize masks.

including long and short suggestions, answers; specifically verify that
text is not clipped in unexpected ways even when rotating to landscape
and back.

Bug: 768374
Test: Please test by displaying all possible suggestions in omnibox,
