[A11y] Update to traces/UMAs used in serialization performance tracking Some parts of accessibility serialiation were not recorded. This CL adds traces and UMAs for: - UpdateTreeIfNeeded - GetUpdatesAndEventsForSerialization - SerializeLocationChanges - BrowserAccessibilityManager::OnLocationChanges It also fixes the trace/UMA ProcessDeferredAccessibilityEvents so that it covers more of thework being done and the UMA is recorded in microseconds. The new version is ProcessDeferredAccessibilityEvents2. Note: a follow-up infra change should update the gasper alerts at infra/config/subprojects/chromeperf-sheriffs.cfg.

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.
