Automatic build profile generation disables `InputMap` class

Tested versions

Reproducible in: 4.3-dev-4, 4.2 branch, 4.2.1-sable

System information

Godot v4.2.1.stable - Debian GNU/Linux testing (gcc12) - Wayland - GLES3 (Compatibility)

Issue description

Automatic build profile generation disables InputMap class. Which should persist almost always especially when user definded custom actions. It can be difficult to determine if user use the action because it can require script parsing (which is also isn't possible for native extensions...) but if user defined custom action it should be easy to detect it

Because of #89477 it looks like is a very systematic problem. I guess it only makes shallow check of used nodes by just traversing all the scenes graphs and doesn't look anywhere else.... ¯\_(ツ)_/¯

Steps to reproduce

1. Create a new project
2. Crete one scene (maybe not necessary)
3. Project->Customize Engine Build Configuration...->Detect from Project
4. Save As
5. Open the saved profile with editor and search for InputMap inside disabled_classes

Minimal reproduction project (MRP)

N/A

Reproduce the issue through Project > Customize Engine Build Configuration > Detect from Project, then save the profile and inspect disabled_classes for InputMap. Trace the automatic profile generation from that workflow and verify that InputMap remains enabled, including when the project defines custom actions.
