luci-base: network.js: consider uci config for Device.getType()/getParent()

For network devices declared in uci but not yet created by netifd, the
runtime status information will be unavailable, causing methods such as
`getType()` to assume plain ethernet interfaces and `getParent()` to fail
resolving parent devices.

Fall back to infer the information from uci configuration settings in such
cases to give accurate type hints to callers.

In particular, this prevents LuCI from turning wireless target networks
containing a to-be-created bridge device into bridges themselves.
