Using {X,Y}_POSSIBLE_NAMES when opening a CSV file fails to attach geometries to features

[nirvn]

What is the bug or the crash?

When using the {X,Y}_POSSIBLE_NAMES ogr driver options when opening a CSV file fails to attach geometries to features. It's quite odd as the vector layer properties window does show a proper extent matching the point values.

Guestimated problem: those driver options aren't passed to the feature iterator. If that's the case, it's a pretty serious issue.

Steps to reproduce the issue

Test dataset:
test.csv

1. Add the following test.csv as a vector layer via the data source manager, and set the X_POSSIBLE_NAMES to 'Longitude' and Y_POSSIBLE_NAMES to 'Latitude'
2. Right click on the vector layer, and select the 'zoom to layer(s)' action
3. Notice how no points are displayed on the map (bad)
4. Open the vector layer properties dialog and go to the general panel
5. Notice how there's an extent shown (good)

@rouault , I'm becoming increasingly certain we're not passing the open options to the QgsOgrFeatureIterator, which I assume most lead to more problems than just this CSV issue.

OK, identified the problem, fix to come.
