    Add Hebrew and Arabic; rework Italic (microsoft#511)

    Major update!

    This update includes the brand new Arabic and Hebrew language coverage,
    along with a variety of bug fixes to the upright and italic fonts. There
    has also been a major overhaul of the Cascadia Code Italic lowercase to
    make the forms align better with our vision for the font. Enjoy :).

    Supersedes microsoft#491

    Cascadia Code
    * [x] Closes microsoft#84 - Arabic language support added!
    * [x] Closes microsoft#465 - Hebrew language support added!
    * [x] Closes microsoft#499 - Adjusted base mark positions / set others to be
      ignored in propagateAnchors

    Cascadia Code Italic
    * [x] Closes microsoft#470 - Adjusted slant on cursive forms to feel a bit better
    * [x] Closes microsoft#468 - Moved cursive forms to `ss01` / `salt` feature
    * [x] Closes microsoft#507 - Changed bar / broken bar to be upright for better
      clarity. All ligature forms adjusted.

    Both
    * [x] Closes microsoft#494 - Adjusted `ƒ` in both upright and italic

    - Arabic (and Urdu) support added (design by Mohamad Dakak). See [the
      Arabic features PDF] for the exciting new Arabic ligature
      functionality used in Cascadia Code that gives the font greatly
      improved readability and feel more more akin to a text typeface. Don't
      want all that? Don't worry, Cascadia Mono will house a normal version
      of Arabic.

    - Hebrew support added (design by Liron Lavi Turkenich)
    - Fixing a bug in the ccmp feature file and added ccmp to the feature
      set in the build script.
    - Deleting the (unused) liga feature file
    - Vika has reviewed and improved some forms in Cascadia Code upright.
    - /f, /l, /s, /r (and related forms) have been updated to follow more
      'generic' forms. Previous versions have been moved to ss01 / salt OT
      features.

    - Changed design of `ƒ` in upright to align better with the standard
      `f`. In the italic, the `ƒ` has been changed to follow the cursive
      version. When `ss01` is applied, the design of the `f` and `ƒ` are
      swapped, and if the `locl` EWE language setting is applied, the 'f'
      swaps for a straight descender version (with cursive `ƒ`).
      Complicated, but achieves supporting everything.

    - Entry and exit strokes across the italic lowercase have been rounded
      to better achieve the fun / playful design language that we intended
      for the italic. Other skeletons have been modified as necessary.
      Cyrillic has also been updated for better consistency with the new
      design.

    - Greek lowercase has been updated per feedback from Gerry Leonidas to
      be more cohesive (No longer a mix between a Monday and Friday font.
      All Friday, all the time)

    ## Validation Steps Performed
    All updated reviewed, hinted, and reviewed again :)
