Build: add scripts to build dependencies for Windows and macOS.

Note these are intended for platform maintainers, we do not intend to
support users making their own builds with these. For that precompiled
libraries from lib/ should be used.

Implemented by Martijn Berger, Ray Molenkamp and Brecht Van Lommel.
