Detail ways to create a C++ binding

[boulabiar]

I opened this issue to discuss ways to create C++ bindings for lvgl.

I don't think the bounty will do it, especially with the conditions that it should be perfect and with examples.. So let's discuss how to do the binding and start with simple examples so it can be done one step each time.

Can we generate code from the rust bindings ? so we have similar APIs ?
