/**
  Allocates and returns a Null-terminated Unicode <ConfigHdr> string using routing 
  information that includes a GUID, an optional Unicode string name, and a device
  path. The string returned is allocated with AllocatePool().  The caller is 
  responsible for freeing the allocated string with FreePool().
  
  The format of a <ConfigHdr> is as follows:

    GUID=<HexCh>32&NAME=<Char>NameLength&PATH=<HexChar>DevicePathSize<Null>

  @param[in]  Guid          The pointer to an EFI_GUID that is the routing information
                            GUID.  Each of the 16 bytes in Guid is converted to 
                            a 2 Unicode character hexadecimal string.  This is 
                            an optional parameter that may be NULL.
  @param[in]  Name          The pointer to a Null-terminated Unicode string that is 
                            the routing information NAME.  This is an optional 
                            parameter that may be NULL.  Each 16-bit Unicode 
                            character in Name is converted to a 4 character Unicode 
                            hexadecimal string.                        
  @param[in]  DriverHandle  The driver handle that supports a Device Path Protocol
                            that is the routing information PATH.  Each byte of
                            the Device Path associated with DriverHandle is converted
                            to a two (Unicode) character hexadecimal string.

  @retval NULL   DriverHandle does not support the Device Path Protocol.
  @retval NULL   DriverHandle does not support the Device Path Protocol.
  @retval Other  A pointer to the Null-terminate Unicode <ConfigHdr> string
