MDEV-41540 filesort assert crash on a huge sort key
sort key could go over 4GB making sort length to wrap around. let's limit sort key length by 2GB - still ridiculously unrealistically large but far enough from 4GB so that any additions in the code below would still be safe. The error is somewhat confusing, but, again, only someone who pushes the margins to exploit memory bugs will ever see it. Additionally min_sort_memory calculations are done as uint and can wrap around too, allocating later over 4GB memory not constrained by @@sort_buffer_size
