Nightly (#8763)

* Expose feature points in BabylonJS as a native extension.

* Expose setFeaturePointCloudEnabled in XRSession, and add it to the startup routine for the feature

* Add some comments and minor cleanup

* Fix some minor spacing issues

* Add id to feature point data.

* fix indexing of confidence value and ID.

* Maintain feature point cloud across frames, signal with our collection every frame.

* Change onFeaturePointsUpdatedObservable to signal with a list of updated Ids so that we can keep track what has changed between frames.

* Fix doubled size array from doing both a distinct size declaration and .push.

* Add in doc describing implementation of FeaturePoints into LibDeclarations.

* Cleanup, make exposed array readonly and use private member variable to do internal accounting.

* Updating What's new, and move private member variable to unbreak typedoc.

* Apply suggestions from code review
