Message:

Emoji: Optimize emoji loader with sessionStorage, willReadFrequently, and OffscreenCanvas.

• Use sessionStorage to remember the previous results of calls to browserSupportsEmoji() for 1 week.
• Optimize reading from canvas by supplying the willReadFrequently option for the 2D context.
• When OffscreenCanvas is available, offload browserSupportsEmoji() to a web worker to prevent blocking the main thread. This is of primary benefit to Safari which does not yet support willReadFrequently.
• Remove obsolete support for IE11 since promises are now utilized. Nevertheless, ES3 syntax is maintained and IE11 will simply short-circuit.

Fixes #58472.
