drivers/usbdev: re-assert soft connect in cdcecm/cdcncm disconnect() 
The USB device controller drivers invoke CLASS_DISCONNECT() on every
USB bus reset, and a bus reset is the first step of normal host
enumeration.  Every other class driver (cdcacm, usbmsc, rndis)
re-asserts DEV_CONNECT() at the end of its disconnect() handler so
that the device remains attached; cdcecm and cdcncm did not, so on
controllers that soft-disconnect around bus reset (e.g. rp2040, which
drops the pull-up in its bus-reset handler) a standalone CDC-ECM or
CDC-NCM device is left soft-disconnected by the first bus reset and
never enumerates on the host.

Mirror the cdcacm behavior and perform the soft connect in the
disconnect() methods, unless part of a composite device (composite.c
already re-connects in its own disconnect handler).

Fixes the standalone CDC-ECM case of issue #15880.

Validated on raspberrypi-pico (RP2040): with this change a standalone
CONFIG_NET_CDCECM device that previously never appeared on the host
enumerates via cdc_ether and pings with 0% loss.  cdcncm has the
identical defect and receives the identical fix.
