ContainerTiming: add initial buffering support

As in other performance events, store ContainerTiming events that
happen before registering a PerformanceObserver, and read them
when setting the PerformanceObserver with the "buffered" parameter.

Explainer: https://github.com/bloomberg/container-timing/blob/main/README.md
Chromestatus: https://chromestatus.com/feature/5110962817073152
I2P: https://groups.google.com/a/chromium.org/g/blink-dev/c/J-WxY0w7bNk/m/VkqnomK-CAAJ

Additional WPT tests provided for testing the buffering capability.

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.
