findsOpsInRegistryWithIntermediate(): restrict to using known source/…

…target CRS that have the same originating authority

Fixes https://lists.osgeo.org/pipermail/proj/2024-September/011531.html
i.e.
```
projinfo -s EPSG:4269 -t EPSG:6318 --3d --spatial-test intersects
```

The fix consists in making sure that we recognize that the 3d-promoted
object EPSG:4269 (NAD83(86)) is still linked to EPSG, and thus discard
ESRI 3D objects in findsOpsInRegistryWithIntermediate()

Fixes a "regression" of OSGeo#4244
(one could argue which of the results is the best, given that NAD83(86)
as a 3D geographic CRS has no solid foundation)
