NetworkPkg: Add IPv6 DUID configuration support using platform PCD.
The code today always uses DUID-UUID unless there is an error in reading the UUID, which results in falling through to DUID-LLT. This change allows the platform to control the DUID method (DUID-UUID or DUID-LLT) using a platform dynamic PCD.
