Sometimes, users don't have a recent enough version of wayland-protocols to build Mesa. But these days, Meson's WrapDB has a wrap that's more than new enough for our needs. If we add the wrap-file to the subprojects folder, we'll download a more recent wrap if the installed version is too old (or doesn't exist at all).
