M7: Hebrew in Add text (#128) (#2109)

Browse Source 
Add text and page_add_text draw Hebrew with the craft-fonts Hebr face
(Noto Sans Hebrew) through the shaped path Arabic and Thai already use:

- pdfcraft-fonts: ShapedScript::Hebrew, shape_hebrew and hebrew_has.
  Grapheme clusters keep points and cantillation marks on their letter.
- pdfcraft-edit: Hebrew paragraphs are laid out with UAX #9 like Arabic;
  spaces and punctuation between Hebrew letters take the Hebrew face.
  first_undrawable refuses Hebrew the face can't draw (or without the
  face) instead of writing "?"; existing items stay movable without it.
- Type 3 glyphs with ToUnicode and per-line ActualText, so extraction,
  search and the editor get typing order back.

Regular style only, as for Arabic and Thai.
