Implement Feature Build Profiles

Browse Source 
This PR is a continuation of #50381 (which was implemented exactly a year ago!)

* Add a visual interface to select which classes should not be built into Godot (well, they are built if something else uses them, but if not used the optimizer will remove them out).
* Add a detection system to scan the project and figure out the actual classes used.
* Added the ability for SCons to load build profiles.

Obligatory Screen:

A simple test with a couple of nodes in the scene resulted in a 25% reduction for the final binary size

TODO:

* Script languages need to implement used class detection (left for another PR).
* Options to disable servers or server functionalities (like 2D or 3D physics, navigation, etc). Are missing, that should also greatly aid in reducing binary size.
* Options to disable some modules would be desired.
* More options to disable drivers (OpenGL, Vulkan, etc) would be desired.

In general this PR is a starting point for more contributors to improve and enhance this functionality.
