Qt package: Add Windows Port (#46788)

Also adds support for Paraview and CMake to build with Qt support on
Windows.

The remaining edits are to enable building of Qt itself on Windows:

* Several packages needed to update `.libs` to properly locate
  libraries on Windows
* Qt needed a patch to allow it to build using a Python with a space
  in the path
* Some Qt dependencies had not been ported to Windows yet
  (e.g. `harfbuzz` and `lcms`)

This PR does not provide a sufficient GL for Qt to use Qt Quick2, as
such Qt Quick2 is disabled on the Windows platform by this PR.
