Merge #15801: Bugfix: GUI: Options: Initialise prune setting range before loading current value, and remove upper bound limit

Browse source 
8a33f4d63f GUI: Options: Remove the upper-bound limit from pruning size setting (Luke Dashjr)
4ddeb2f860 GUI: Options: Set the range of pruning size before loading its value (Luke Dashjr)

Pull request description:

  This fixes two bugs:

  1. The prune setting range was set *after* loading the current value. If users had a prune of (eg) 200, it would get limited to 99 before the range was raised. This is fixed by setting the range first.
  2. The prune setting was limited to <= the chainparams' "assumed blockchain size". There's no reason for this limit (the UX is the same either way), and there are use cases it breaks (eg, setting a prune size such that it begins pruning at some future point). Therefore, I raised it to the max value.

  This is a daggy fix, so should cleanly merge to both master and 0.18 branches.
