Add function to adjust build range

[lL1l1]

Currently it is only build range is only adjustable in unit blueprints using MaxBuildDistance. It would be nice to be able to change the build range using a function like Unit:SetMaxBuildDistance(number) to be able to create enhancements/buffs that adjust the build range of a unit.

Hi, I noticed this feature request might be related
to a bug I've been looking into.

When an engineer receives a build order outside their
build range, they walk too close to the target instead
of stopping at the edge of MaxBuildDistance.

When the build order is placed inside the range, the
engineer starts building immediately without moving -
which is the correct behavior.

The inconsistency suggests the movement target
calculation for out-of-range build orders does not
correctly use MaxBuildDistance as a stop radius.

Is this related to what you had in mind with
SetMaxBuildDistance()? And would fixing this movement
calculation be part of the implementation?
