    ci: Add a macos build
    
    Most of this is cribbed from glib.
    
    We don't use COMMON_MESON_FLAGS here, since disabling
    -Werror one subproject at a time is too painful for
    all the promoted sub-sub-projects. This needs a better
    solution in meson.
    
    Since this is a full rebuild of the entire stack, limit
    this to master and merge requests.
