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

Browse Source 
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.
