Subject: [PATCH] [ArchStairs] Fix-hideSubobjects

Arch Objects usually has hideSubobjects to hide children.

ArchStairs does not have this and children (e.g. Additions, Subtraction [Railing to be added]) does not hide; this fix the problem.

Other Associated Inconsistency
- Other movable childre and visibility behaviour (like Railing of Stairs should be children) as discussed in https://forum.freecad.org/viewtopic.php?p=844965#p844920 would be added in subsequent PR
