Gitter sunsetting: Pass feature flag though to everywhere we use getRoomUpgradeHistory

Towards MSC3946

Pass the MSC3946 feature flag in wherever we call getRoomUpgradeHistory.

There may be a unified way we should approach this, but the code locations that call this function are here:

• src/stores/BreadcrumbsStore.ts
• src/stores/spaces/SpaceStore.js
• src/utils/leave-behaviour.ts
• src/components/structures/SpaceHierarchy.tsx

Actually, this is better seen as part of #24417 since they overlap.
