[E2E] Track native transitions, add DrawNative Feature.

Adds a Tab change observer to notify the E2E controller that it might
need to switch between ToNormal and ToEdge.

The new logic is to draw all native pages and the Tab Switcher ToEdge, when this new Feature is enabled: DrawNativeEdgeToEdge.

TODO: refactoring for better test coverage.

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.
