curl: create easy handles on-demand and not ahead of time

Browse Source 
This should again enable crazy-large download ranges of the style
[1-10000000] that otherwise easily ran out of memory starting in 7.66.0
when this new handle allocating scheme was introduced.

Reported-by: Peter Sumatra
Fixes #4393
Closes #4438
