[chip-tool] Add flag to enable server interactions (#24695)

Add "--advertise-operational" flag to the chip-tool's
"interactive" command that enables server features,
including advertising operational services. This feature
is needed to test persistent subscriptions using chip-tool,
which requires that chip-tool be discoverable after the
publisher node reboots.
