[WebAudio] Implement the AudioContext interrupted state

This CL implements the AudioContext "interrupted" state and the
interruption methods behind a feature flag. This feature's explainer can
be found at:
https://github.com/MicrosoftEdge/MSEdgeExplainers/blob/main/AudioContextInterruptedState/explainer.md

Even though this feature is not fully testable by using WPTs (it needs
an external agent/feature to cause the interruption), unit tests have
been added to make sure that the feature behaves in accordance to the
explainer.

This feature can be controlling by enabling the
AudioContextInterruptedState flag. The following cmd line can be used:
chrome.exe --enable-features=AudioContextInterruptedState

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.
