[Tab Group Sync] Only create new tab group current window is active

For incoming tab group updates from sync, if we have more than one
activity running, we should create the local tab group in only
one of them. We should never create the tab group in both windows.
This CL does that by checking
ApplicationStatus#getLastTrackedFocusedActivity which is guaranteed to
be the last focused activity (in case of more than one activity), or
the single chrome activity that is running and still not destroyed.

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.
