WSM: Support add/update/enable network in any state

WifiConfigManager can support network addition/updation as soon as the
config store is read at bootup. So, add support for it in WSM.

ENABLE_NETWORK handling is duplicated because when wifi is off, we don't
want to trigger a connection request (when disableOthers is true).
