Missing gdscript functions

I notice we're missing some print functions that are in gdscript. Namely [prints](https://docs.godotengine.org/en/stable/classes/class_@gdscript.html#class-gdscript-method-prints), [printt](https://docs.godotengine.org/en/stable/classes/class_@gdscript.html#class-gdscript-method-printt), [print_debug](https://docs.godotengine.org/en/stable/classes/class_@gdscript.html#class-gdscript-method-print-debug), and [print-stack](https://docs.godotengine.org/en/stable/classes/class_@gdscript.html#class-gdscript-method-print-stack).

When writing gdscript I use `prints` in every situation (as it inserts spaces between arguments, just like `console.log` in JavaScript), so I noticed it quickly when trying this project.

Also I'm not sure that `print` is working as expected. It is supposed to accept and print any number of arguments, but in my testing it only prints the first:

```typescript
// this prints: "a"
godot.print("a", "b", "c")
```

The typings for `print` seem correct though:

```typescript
function godot.print(...args: any[]): void
```

Start by locating the binding behind godot.print and compare its argument handling with the GDScript functions linked in the issue. Check how print currently handles multiple arguments, then trace the corresponding API entry points for prints, printt, print_debug, and print-stack. Done means the four functions are available and print accepts all supplied arguments as described.
