scons command examples compiles without debug symbols

**Your Godot version:**
Godot 4

**Env:**
Windows 10, Visual Studio 2022

**Issue description:**
scons command examples compiles without debug symbols, this can be frustrating, because Visual Studio breakpoints don't work this way. I expected breakpoints to work out of the box (as expected in the documentation).

I think ```dev_build=yes``` argument will be included in examples, because building engine is almost always for development/debugging purposes. And investigating into scons can take some time, to figure out a debug build option.

```scons platform=windows vsproj=yes``` - will compile engine without debug symbols
```scons platform=windows vsproj=yes dev_build=yes``` - will compile engine **_with_** debug symbols
