Editorial: Prefix names of intrinsics

[linusg]

Closes #842.

Not sure if the same naming scheme is appropriate for %SegmentIteratorPrototype% and %SegmentsPrototype%, but happy update those as well if wanted.

[ljharb]

The rule is that anything that's accessible off of a top-level intrinsic, should be - so if %Segments% exists, then i'd expect %Segments.prototype%, etc.

[linusg]

%Segments% doesn't exist, the object is created directly in an AO (https://tc39.es/ecma402/#sec-createsegmentsobject):

1. Let internalSlotsList be « [[SegmentsSegmenter]], [[SegmentsString]] ».
2. Let segments be OrdinaryObjectCreate(%SegmentsPrototype%, internalSlotsList).

Same for %SegmentIteratorPrototype% (https://tc39.es/ecma402/#sec-createsegmentiterator):

1. Let internalSlotsList be « [[IteratingSegmenter]], [[IteratedString]], [[IteratedStringNextSegmentCodeUnitIndex]] ».
2. Let iterator be OrdinaryObjectCreate(%SegmentIteratorPrototype%, internalSlotsList).

[ljharb]

Gotcha; then those two would remain as-is.

Thanks, this is great! I'm thinking it also needs to include oldids attributes for preserving any current inbound links, and possibly renaming %SegmentsPrototype% to %IntlSegmentsPrototype% and %SegmentIteratorPrototype% to %IntlSegmentIteratorPrototype% as well.

[linusg]

Done! I don't think any IDs are changed by the first commit (all links reference the public names already), but I've included oldids in the second change.
