[gimp/wip/Jehan/testing-msys2-win-CI: 1/2] build: use msys2 packages as source for the Windows CI.

[Jehan <jehanp src gnome org>]

commit 8398c83c23359426b7bdeaab1fb50663381940e2
Author: Jehan <jehan girinstud io>

    build: use msys2 packages as source for the Windows CI.
    
    This is a new feature I implemented in the crossroad cross-compilation
    tool. Msys2 repository has more packages and they are more up-to-date
    compared to Fedora and Suse cross-built packages (the 2 other available
    sources for pre-built Windows packages).
    This allows to simplify a lot the dependency preparation for the Windows
    CI, and speed things up.
