[graphemecluster (graphemecluster)]

General Information

PR separated out from #49855, because there might be some members expecting smaller PRs. As mentioned in the comments from the big PR, whether to review a single, large PR or 6 smaller PRs is up to the TypeScript Team to decide. I couldn't have found a better way for this; hopefully this will not bring any trouble to the Team.

This PR partially fixes #49773.
For details and the track list about the changes, please see #49773.
