REPL/Console Commands support

### Godot version

4.3.stable

### VS Code version

1.93.1

### Godot Tools VS Code extension version

2.3.0

### System information

Windows 11

### Problem statement

While debugging, VS Code allows you to type commands into the console, which currently (in my testing) does nothing.

### Proposed solution

Godot 4.4 will be getting a REPL, so I would like for VS Code's console to have similar functionality!
