[Android] Shell Action Bar behavior same as chrome

[Android] Shell Action Bar behavior same as chrome

Added styles to Chrome Shell and Content Shell, so that the
behavior of Action Bar in shell apks are same as Chrome
Browser. In Chrome Browser, the Action Bar overlaps the
URL Bar but in Shell apks, the Action Bar pushes the Activity
Window downwards to make space for the Action Bar

What happens if you attempt to long press on the text in the url bar
with this change?  Does the action bar overlap it?

If I recall, we had to do special magic when copying from the URL bar
with a change similar to this in Chrome, and I wouldn't want to add
that kind of cruft to these test shells if it does.

Yes, Action Bar overlaps the url bar when we long press on url bar.

Currently, android does not allow changing of styles dynamically.
Otherwise, we could have changed the "android:windowActionModeOverlay" property
programatically to false when we show the Action Bar in
SelectActionModeCallback,
and set it to true when it is destroyed. This could have been one way of
bringing in the same behavior of Action Bar as Chrome.

Do you have any suggestions regarding this?
