[imgui] Split bindings to multiple features (#12329)

* [imgui] Split bindings to multiple features

See #12250.

I tested all the features on x86-windows, x64-windows, x64-windows-static and x64-linux triplets. Everything build fine except:
- dx12-binding on x86-windows. There's an issue opened about it here : https://github.com/ocornut/imgui/pull/2406
- allegro5-binding on x64-linux, because the current allegro5 port fails to build on this platform.

Contrary to the previous port which simply copied the sources to a specific folder, bindings are now compiled with their dependencies. The only exception is Marmelade, because there's no port available for it yet.

Unfortunately, I can't test the OSX and metal bindings. If someone using this platform could test it, it would be very much appreciated. :)

* [imgui] Move port files to the correct folder

* Update ports/imgui/CONTROL
