[AX-Unserialize] Implement alternative Unserialize approach for AXTree

This CL switches the order of iterations for the AXTree's
Unserialize method. Profiling suggested that by turning our
loops "inside-out", we could improve performance. The idea
being that it is easier to iterate over the node data and
IDs than it is over the AXTreeObservers. Local testing has
showed promising results.

We add this implementation behind the feature flag added in
the previous CL, and include a unit test for confidence.

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.
