Python screens: ship Pillow with the Windows build, and the screen module for Pillow 10+

- The Windows build job installs Pillow into the Python 3.14 whose Lib, with
  site-packages, CMake copies next to the executable as python64\Lib, as the
  Linux job already does; the README says the same for a local build.
- Both build jobs copy staticFiles/python/local (the Python 3 version of the
  module every cab screen subclasses) into python/local of the build.
- The module puts back what Pillow 10 removed and the screen scripts use:
  ImageFont.getsize() and ImageDraw.textsize() on top of getbbox() /
  textbbox(), and Image.ANTIALIAS as LANCZOS. With an older Pillow nothing
  changes.

Part of #300.
