Implement console.context() #29560
Description
console.context(label) returns a new object with a lot of the console members. Messages emitted from calling the method from this created object can carry the context name, which can be used to categorize/filter them more easily.
console.context is available in Chrome and Node (even though logs emitted from it are not visible, see nodejs/node#56634), and is currently being implemented in Firefox (https://bugzilla.mozilla.org/show_bug.cgi?id=1948870)
See the whatwg issue (whatwg/console#193) and the (WIP) PR to specifiy it (whatwg/console#244)
