Arrow widget used for history navigation UI was previously inherited
from ChipView. This CL introduced its own UI widget class that simplifies
APIs and has the right style for the design. It will also be used as
a base class for other elements in the long term design. Also contains:

- centered the arrow in the round icon
- verified the style in dark mode
- icon color is tinted by default to match that of the text
- long text is ellipsized
