Fix left/top in ViewNode for suppressed parents

If parents of a view got suppressed in the autofill structure the left
and top value are not relative to their direct parents anymore. They
need to be relative to the next non-suppressed parent.

This does not change any values for assist structures.

Fixes: 36060132, 37444334
Test: CtsAutoFillServiceTestCases + new ones that check for the left and
      top parameters of view nodes.
