Bundle newer meson

We will rebase mutter to GNOME 49, where at least meson 1.5.0 is
required.

That requirement is due to the port to meson's wayland module for
generating protocol headers, so reverting the change would result
in conflicts in all future protocol-related backports.

To avoid this, use a recent-enough bundled meson version for the
build.

It's not pretty, but it works…
