feat: add support for enabling ORDER BY on non projected columns

[gaurav274]

In response to PR #1147, we've introduced support for the use of ORDER BY on non-projected columns

SELECT name FROM meme_images
ORDER BY Similarity(SiftFeatureExtractor(Open("{}")), SiftFeatureExtractor(data))
LIMIT 1;

SELECT FaceDetector(data) FROM MyVideo WHERE id < 5 order by scores;

SELECT AirForecast(12) order by y;

Select name FROM meme_images ORDER BY name;

The following query won't work.

Select name AS n FROM meme_images ORDER BY n;

Currently, we execute projection as the last operation. Only when a function expression is present it is executed before projection, allowing its use in ORDER BY. A complete fix will require us to redesign the binder. Right now, we've decided to defer this task because there is no urgency to support it.

Have you tried running long integration tests to verify the fix?
