Support the SkipAd media session action. This skipad action allows Chrome to show a button in the system media controls or in the PiP window.
This feature was initially proposed and implemented four years ago but remained disabled due to a lack of practical use cases. It already received LGTM from the Blink dev group back in February 2019 (see intent email for details: https://groups.google.com/a/chromium.org/g/blink-dev/c/l6sW0G4jzhE/m/2bi3c8dZDwAJ). Given our team's (chromeOS UI team) plan to add this "skipAd" feature in our upcoming project, we are now proposing to enable it.
