MdeModulePkg: Define a general function to create DNS QName
This patch is used to define a general function to create
DNS QName.
QName is a domain name represented as a sequence
of labels, where each label consists of a length octet
followed by that number of octets. The domain name terminates
with the zero length octet for the null label of the root.
