[rlgl] Implement vertex normals for RLGL immediate drawing mode (#3866)

Browse source 
* Fix several non-functional `target_compile_definitions`

* Avoid hardcoding the default vertex attribute locations

* Implement functional `rlNormal3f`

* Add normal definitions for `DrawCube`

* Update the basic lighting example to use `DrawCube` and `DrawPlane`
