[roll] Roll fuchsia Reland "[netcfg] Remove temporary interface name policy"

This is a reland of commit 915c4e2012e68daebb9917557283de5a38b39081

This CL now uses the InterfaceNamingIdentifier to decide whether an
interface is already present and named by Netcfg. This identifier is
based on the device's MAC address, which identifies what device is
connected, rather than where the device is connected. This permits
situations where two interfaces may share the same location, but be
different interfaces, such as a WLAN device and a WLANAP device.

Tested: Locally on a SD to ensure that an AP interface and WLAN
interface at the same topological path could co-exist on the device.

Original change's description:
> [netcfg] Remove temporary interface name policy
>
> Remove the behavior where fallback temporary names would be used for
> interface names if the first attempt to add an interface to the Netstack
> failed. This led to names like "etht0" .. "etht1".
>
> When a device is discovered by the Netstack, get the
> PersistentIdentifier for the device, and determine whether Netcfg
> already knows about that device. If it does, then we will remove the
> existing interface prior to installing the new one. If Netcfg does not
> know about the device, then we do nothing and install the new one.
>
> When a device fails to be added to the Netstack with an AlreadyExists
> error, this indicates the interface was installed from another source or
> an interface was already installed by Netcfg with a different identifier
> that has the same name. In either case, we will reject interface
> installation and log it as an error.
