[arch-general] packaging mingw-w64-gtksourceview5 and mingw-w64-libadwaita

[Sim Tov]

Hello,

I would like to help Gnome Text Editor developers to cross-compile it for
Windows within their CI:

https://gitlab.gnome.org/GNOME/gnome-text-editor/-/issues/149

This might help attract Windows users to Gnome/Linux...

I was looking for a Linux distro that has a solid Mingw-w64 library
collection to use as docker image in CI. Fedora doesn't have mingw-w64-gtk4
while Arch does, so I decided to use the latter.

Dear Arch package maintainers, may I ask you to, please, package the most
recent version of mingw-w64-gtksourceview5 and mingw-w64-libadwaita so I
can go ahead?

I saw this MSYS2 package (they use pacman) that might help you with
compilation flags, etc.:

https://packages.msys2.org/base/mingw-w64-gtksourceview5
https://packages.msys2.org/base/mingw-w64-libadwaita

Thank you!
