meson: add wayland-protocols from meson wrapdb

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).
