The main change here is that collapsed and `text-transform`'d text is computed as it's processed by DOM traversal. This single transformed text is stored in the root of the `InlineFormattingContext`. This will eventually allow performing linebreaking and shaping of the entire inline formatting context at once. Allowing for intelligent processing of linebreaking and also shaping across elements. This matches more closely what LayoutNG does. This shouldn't have any (or negligable) behavioral changes, but will allow us to prevent linebreaking inside of clusters in a followup change.
