Add C/I Workflow for Windows build without using Conda packages

[kordejong]

Download pre-built binaries (and cache them), and build LUE against those.

• Boost: https://sourceforge.net/projects/boost/files/boost-binaries/1.85.0/
• GDAL: https://www.gitinternals.com (contains HDF5!)
• HWLOC: https://www-lb.open-mpi.org/software/hwloc/v2.11

This is enough when not building lue_view.

HPX must be rebuilt with the downloaded HWLOC version. Otherwise Conda is still needed. Maybe copy the current windows.yml file and adjust it.

When working on this, talk to @kordejong first. He has all of this working on his local machine.
