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.
