Subject: [PATCH] Change stale_bus_members to work around MSVC issue

Somehow, MSVC vector gets corrupted in certain cases.  While the
mechanism is unclear, using an unordered_set avoids this problem

Fixes https://gitlab.com/kicad/code/kicad/-/issues/15217

(cherry picked from commit 7bd399235064b3f321792b2fbe40af85ff2ac3f0)
