Upstream contributions to jfx.incubator.richtext

Gaps in the incubator RichTextArea that html-to-node currently works around (split from #2; details and workaround pointers there). Each landed OpenJFX feature deletes a workaround here:

1. Character-level link attribute with activation handling (currently: custom HREF attribute + getTextPosition on click)
2. Inline node/image embedding as first-class model feature (currently: addNodeSegment, view-only model only)
3. Baseline-shift / vertical-align character attribute (currently: sub/sup lose their shift, font-size only)
4. Numeric font weights (currently: CSL's font-weight: 100 collapses to normal/bold)
5. Styleable selection/caret colors on the control (e.g. -fx-selection-fill, -fx-caret-color) instead of Modena rules on skin-internal sub-nodes — see the analysis in Evaluate a RichTextArea-based renderer (JavaFX incubator) as alternative to FxRenderer #2
6. A lean read-only viewer mode without caret/edit overhead

I am very interested in your experience and feedback, especially during the incubating period when we have more freedom to adjust the APIs and fix the early deficiencies.

Apart from inline editable tables, did you find any missing functionality or APIs?
