ModemManager: broken in 22.03/23.05 and netifd reconnect issue

Firstly, ModemManager is broken in 22.03 because modem disconnect does not reach through to netifd absent this patch from @aleksander0m: https://github.com/openwrt/packages/commit/bc754f31cfdb004eefa43038f8f0827922107fc6

In short, ModemManager sees the disconnect, but netifd does not and the output of e.g. 'ifstatus' or 'ip addr show dev' is wrong (reflecting the old connected state and not updated to reflect disconnection). See e.g. here: https://github.com/openwrt/openwrt/issues/8368#issuecomment-1299719052.

So ModemManager in 22.03 needs to be updated to fix this.

Secondly, even with the above patch in the ModemManager version on OpenWrt master, upon disconnection we see:

Wed Nov  2 20:38:54 2022 daemon.info [2716]: <info>  [modem0] state changed (connected -> disconnecting)
Wed Nov  2 20:38:54 2022 daemon.info [2716]: <info>  [modem0] state changed (disconnecting -> registered)
Wed Nov  2 20:38:54 2022 daemon.info [2716]: <info>  [modem0/bearer3] connection #1 finished: duration 121s, tx: 258333 bytes, rx: 371928 bytes
Wed Nov  2 20:38:54 2022 user.notice modemmanager: interface wan (network device wwan0) disconnected
Wed Nov  2 20:38:54 2022 daemon.notice netifd: Interface 'wan' has lost the connection
Wed Nov  2 20:38:54 2022 daemon.notice netifd: Network device 'wwan0' link is down
Wed Nov  2 20:38:54 2022 daemon.warn dnsmasq[1]: no servers found in /tmp/resolv.conf.d/resolv.conf.auto, will retry

And so although now with the patched version of ModemManager netifd sees the disconnect, netifd does not actually reconnect.

This is using /etc/config/network:

config interface 'wan'
        option proto 'modemmanager'
        option device '/sys/devices/platform/1e1c0000.xhci/usb2/2-1'
        option auth 'pap'
        option iptype 'ipv4v6'
        option apn 'xx
        option username 'yy'
        option password 'zz'

Start with the ModemManager disconnect log and the /etc/config/network modemmanager interface shown in the issue, then compare the referenced package patch with the 22.03, 23.05, and master behavior. Reproduce a modem disconnect and verify that netifd updates its state and reconnects; done means both behaviors work consistently.
