ci: vcpkg improvements

* Upgrade to 2025.07.25
* Configure vcpkg settings in vcpkg.json, this avoids needing to
  duplicate the vcpkg hash used in several places, and also avoids
  needing to set overlay ports/triplets directories from CMake
* Add caching workaround so that builds won't take forever every time
* Build on windows-2025
