### Issue description

When creating TileSets from code, the TileSet's `add_source(source: TileSetSource, atlas_source_id_override: int = -1)` method is supposed to accept gdscript int (which is a signed 64-bit int), however feeding it with integers above C++ signed int (>2147483647) will result in a failure - in fact the actual return int (which is supposed to be the source_id override) is equal to 0 and not -1 as method description implies should be the case when the source could not be added. 

PS. Why do I need such huge numbers for tileset sources? I'm adding tilesets from a set of config text files and I'm hashing some parameters from it (via String `hash()` method which returns a 32-bit int) to use as a source_id for the tile set source. I will workaround that one way or another, of course, it's only marginally annoying :) 




### Steps to reproduce

```
var tileset : TileSet = TileSet.new()
var tileset_source : TileSetAtlasSource = TileSetAtlasSource.new()
	
var result : int 
	
result = tileset.add_source(tileset_source, 2147483647)
print("Adding source ID 2147483647 (int) -> ", result) # OK for signed int
	
result = tileset.add_source(tileset_source, 2147483648)
print("Adding source ID 2147483648 (signed int +1) -> ", result) # NOK 
```
