Merge branch '17932-move-to-project-dropdown' into 'master'

Move to project dropdown with infinite scroll for better performance

## What does this MR do?

On the Move dropdown on the edit issue page we introduced infinite scrolling to just return a limited number of projects, 50 items. So if the user can move the issue to 50 or more items when scroll down on the list a new set of projects will be requested to the server.

## Are there points in the code the reviewer needs to double check?

## Why was this MR needed?

See #17932

## What are the relevant issue numbers?

Closes #17932

## Screenshots (if relevant)

## Does this MR meet the acceptance criteria?
