Use archived gas mixture in gas exchange comparison (#32088)

Use archived gas mixture in gas exchange comparison (#32088)

The comparison for doing gas exchange used current and not archived
moles. This could lead to update order-dependent gas spreading effects.

To fix this, convert TileAtmosphere's MolesArchived and
TemperatureArchived to a AirArchived, and use that in the comparison
method.
