Re-land: Make action mode view extend into system insets area

This CL makes the action mode view extend into system insets area if the
insets don't get consumed by its parent container. If the vertical
navigation bar is visible, the action mode view and the action bar will
fit navigation bar, which will align the width of the status bar color
view, and there won't be weird color blending in the corner.

Before this CL, when onConfigurationChanged of an ActionBarContextView
is called, it would read and set the wrong content height. This is
because ActionBarContextView extends AbsActionBarView, but didn't
override onConfigurationChanged which would read ActionBar_height
instead of ActionMode_height. This CL also fixes the issue.
