gdal @3.10.1: mention +kea variant creating a circular dependency in the variant description

[cooljeanius (Eric Gallager)]

gdal's +kea variant description currently reads:

kea: Enable KEA support

However, one thing to note about this variant is that it creates a circular dependency, as kealib depends on gdal, yet the variant description says nothing about this. Compare this to, for example, dbus's +tests variant, which also involves a circular dependency:

# XXX Building with tests enabled causes dbus to link with dbus-glib,
# which it shouldn't do because that port depends on this one: see #30088
variant test description {enable tests (Only Works if dbus is Already Installed)} {
    ui_warn "This variant requires circular dependencies and only works if ${name} is already installed"

    configure.args-replace  --disable-tests \
                            --enable-tests
    configure.args-append   --without-dbus-glib
    depends_build-append    path:lib/pkgconfig/glib-2.0.pc:glib2
    depends_build-append    port:python27 port:dbus-python27 port:py27-gobject3 port:dbus-python
    configure.python        ${prefix}/bin/python2.7
}

It would be nice if gdal's +kea variant could be updated to provide a similar note about circular dependencies.

Ideally, it should be implemented as gdal subport: gdal-kea. I’ll see if that is feasible.
