Subject: [PATCH] [ncp] use OT public link API to get factory-assigned EUI64
 (#4047)

This commit changes the get handler for `SPINEL_PROP_HWADDR` to
use the public OT link API `otLinkGetFactoryAssignedIeeeEui64`
instead of the platform API. It also adds implementation of
this API under `OPENTREAD_RADIO` mode (for RCP build).
