Use the Harmony textfield stack in the add bookmark bubble.

And remove colons from the field labels (both for Harmony
and non-Harmony).

The non-Harmony DISTANCE_CONTROL_LIST_VERTICAL also changes
from 20px (DISTANCE_UNRELATED_CONTROL_VERTICAL) to 8px
(DISTANCE_RELATED_CONTROL_VERTICAL). This avoids excessive
vertical padding between the fields. The result is that the
non-Harmony http-auth and add bookmark dialogs fields get
more compact, which looks OK.

This CL removes anon::UnsizedCombobox in bookmark_bubble_view.cc
and relies on a GridLayout::FIXED (but stretchy) column to
achieve the same result.
