Backed out for causing wpt failures on Android.
L.E. There are more failures related with your changeset and on multiple platforms: https://treeherder.mozilla.org/jobs?repo=autoland&group_state=expanded&resultStatus=testfailed%2Cbusted%2Cexception%2Cusercancel&revision=f8b80c380cc2c238ca9c742801d7c30f881feca8&searchStr=wpt&selectedTaskRun=eFqCiNHfQluPgR5MbK19fw.0

Release Note Request (optional, but appreciated)
[Why is this notable]: This adds a new variety of typed array that is particularly useful for transferring data to the GPU for things like graphics and ai models.
[Affects Firefox for Android]:
[Suggested wording]: Float16Array typed arrays are now supported, along with new DataView methods for reading and setting Float16 values, and a Math.f16round() static method that can be used to round numbers to 16 bits. The new type is useful for sharing data with a GPU, in particular for use cases where it makes sense to trade off precision for memory consumption.

FF129 MDN docs work for this can be tracked in https://github.com/mdn/content/issues/34697. Mostly just release note, removing from experimental features and compatibility data. Docs themselves already up to date.
