Add github actions for vcpkg and disable Alpha Shapes on MSVC
I've added a new file on GitHub to assist in testing compilation with VCPKG. This addition aims to streamline the process and ensure smoother compatibility checks.
Additionally, I disabled the alpha shapes algorithm on MSVC. This adjustment was necessary to address compatibility issues within the MSVC environment (https://github.com/CGAL/cgal/issues/7667).
