[iOS] Check size class for sticky omnibox

The fake omnibox should only be pinned on narrow screens, like portrait
iPhones and multiwindow iPads. Otherwise, the fake omnibox becomes the
real primary toolbar, like on landscape iPhones and full-width iPads.
Instead of just checking the device type, we check the size classes to
determine this.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure .

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.
