5756: Editor: added a goto button r=heinrich5991 a=archimede67

<!-- What is the motivation for the changes of this pull request -->

This feature was also suggested by Pulsar. It adds a button to go to a specified coordinate point by inputting x and y coordinates through a popup window:

The two number inputs are constrained between 0 and the width/height of the map (minus 1). When clicking "Go", it focuses the camera at the center of the tile at these coordinates.

## Checklist

- [x] Tested the change ingame
- [x] Provided screenshots if it is a visual change
- [ ] Tested in combination with possibly related configuration options
- [ ] Written a unit test (especially base/) or added coverage to integration test
- [ ] Considered possible null pointers and out of bounds array indexing
- [x] Changed no physics that affect existing maps
- [ ] Tested the change with [ASan+UBSan or valgrind's memcheck](https://github.com/ddnet/ddnet/#using-addresssanitizer--undefinedbehavioursanitizer-or-valgrinds-memcheck) (optional)
