QUrl effective TLDs: update table and split into chunks of 64K

The table is there to know which domains are allowed to set cookies
and which are not. There are more than 2000 new entries since the
list has last been generated.
The split to 64K chunks was made because this is the hard limit for
strings in Visual Studio.
