Enable mono editor build in CI

[qarmin]

Depends on #47414 which removes partial editor mono compilation instructions

It would allow to get from CI fully working Godot mono build exactly as in 3.2 branch

[qarmin]

I tested artifacts and seems that editor works fine and can build project

[akien-mga]

I actually broke the Mono build yesterday, #53882 should fix it (at least the current error).

Another proof that we need this finalized and merged :P

[qarmin]

I copied compilation instructions from 3.x branch and looks that now after producing binary, editor freeze when executing unit tests

[qarmin]

Looks that mono build is again broken

Fixed by #54016.

Looks that there is another problem, because entire job freeze for 6 hours and fails - /~https://github.com/godotengine/godot/runs/3914980436?check_suite_focus=true

I tried to add --headless to tests but still I see that this job freeze

You should update main.cpp too:

                // From editor/csharp_project.cpp.
                GLOBAL_DEF("mono/project/auto_update_project", true);

[qarmin]

What should be done here?
I removed this line because i checked that auto_update_project is not used in other files

[akien-mga]

You should remove the dummy define from main.cpp, it's no longer used.

Thanks!
