NetworkPkg: Add dns support for pxe boot based on IPv6.

The BootFileURL option (59) in dhcpv6 is used to deliver
the next server address with bootfile name, as an example
"tftp://[FEDC:BA98:7654:3210:FEDC:BA98:7654:3210]/BOOTFILE_NAME;
mode=octet", it can also be “tftp://domain_name/BOOTFILE_NAME;
mode=octet”, this patch is to support this case.
