Undo what remains of crrev.com/c/5247180

In crrev.com/c/5247180, to address a specific problem in Lacros, an
instance variable called active_task_id_ was introduced in
task_manager_table_model.{h,cc}, alongside a few other helper functions
that were virtual.

Later on, similar problems were addressed for macOS too. As a result,
some code in crrev.com/c/5247180 were then used by both Lacros and
macOS, two separate desktop platforms.

Now that Lacros is sunsetted, this CL aims to undo what remains of
crrev.com/c/5247180. As a by-product, this CL also removes a virtual
function that is now unused by both Lacros and macOS.

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.

If you found a bug, please file it at https://crbug.com/new.
