Implement Field::SetHidden using Field::SetDisplay.chromium/2837

Following up on [1], where the duplicated logic in
Field::SetDisplay was factored out into a helper function,
CL further cleans up a related method: ::SetHidden.

Field::SetHidden(true), for instance, is equivalent
to calling Field::SetDisplay(1), whereas Field::SetHidden(false)
is equivalent to Field::SetDisplay(0);

No behavior change is expected.
