`print()` is no longer sent to Output panel when running project on Android due to debugger connection not working

Android

Issue description

When running an Android application with "remote debug" ticked, Godot would always output print and error messages to the log in the Godot IDE.

We use this extensively in XR where alongside the "verbose" tickbox, we add a lot of extra information through print_verbose.
Even without that a standard Android project would atleast output the standard print lines (such as the "Godot Engine v4.1.1stable..." line).

So for instance running a simple XR project in Godot 4.1.1 stable with verbose enabled and remote debug enabled gives us:

Doing the same in master:

No more log. Same issue applies to normal Android. I have only tested this with gradle builds.

Steps to reproduce

Take a Godot project that can run on Android.

Enable remote debug

Run project on an Android device.

Minimal reproduction project

I think any simple project will do, but I used this for testing:

Same here. Here is the Output when running adb logcat. Maybe it helps somone to figure it out.

I just experienced this bug while doing some particle benchmarks on mobile. (no gradle build)
It's not only the print messages: it seems like the debugger wouldn't attach at all (so no profiling, pausing, stopping at breakpoints).

Thanks for the info! This actually gives me an insight into what the issue may be.

I wonder if this would have been fixed by #84102? Worth checking in 4.2-beta4 when it's out.
