Separate the logic for 3D physics synchronization from 2D physics synchronization

[not502]

In many cases, a project is either fully 3D or fully 2D, meaning that either the 3D physics package or the 2D physics package is unnecessary. I usually remove the packages I don't need. I noticed that in this plugin, the logic for 3D physics synchronization and 2D physics synchronization is written together. When I imported this plugin, I encountered many errors. Of course, fixing them is simple—just delete the 2D physics parts. However, if I want to update the plugin used in the project, I have to repeat this process. Could you provide a macro, similar to ENABLE_PHYSICS3D and ENABLE_PHYSICS2D, to easily disable certain unnecessary modules?
