No way to start Profiler before starting game

[cosmoddd]

Godot version

4.0 Beta 16

System information

Windows 11 Vulkan

Issue description

In the online manual, it states:

To begin profiling, click on the Start button in the top-left. Run your game and data will start appearing. You can also start profiling at any time before or during gameplay, depending on if you want.

I want to be able to profile my game's startup time to suss out any bottlenecks during startup.
However, the option to start profiling before the game as it starts is not possible in the current 4.0 build. In 3.x, this option is available.

Steps to reproduce

Click on the Debugger tab at the bottom of the screen.
Click on the Profiler tab in the Debugger window.
Notice that you cannot press "Start".
Start any scene.
Notice that you can now press "Start"
Stop the scene.
Notice that you can no longer press "Start" on the profiler.

Minimal reproduction project

This issue is apparent regardless of the project.

Related to #71111 (profiler button being grayed out)

As this is the 4.0 build (# 71111 is still on 3.x) and the Profiler does work once the game is running, I'm not sure the two issues are related.

Whoops, didn't notice THAT. Right.

The lack of autostart functionality is being tracked in godotengine/godot-proposals#6017.

cc @Faless, as they rewrote the editor debugger for 4.0.

I think this was changed in #70151 which fixed some other inconsistencies with the profiler Start/Stop buttons.
Personally I think implementing an autostart feature would be a better solution, but I'm guessing just allowing it to be started again ahead of launch would be an easier temporary fix as this is how it used to work.

@lostminds There is a autostart PR for this feature. I am waiting for review.

This was implemented by #96759 (with slightly different UX), closing.
