I tested this with CMake. I don't know if the examples makefile
currently handles this case.

Example is intended for `PLATFORM_DESKTOP` only and OpenGL 3.3 Core profile.

* Hotfix for Vector2LineAngle(), should probably be reviewed along with the rest of raylib angle functions to determine what coordinate system we want.

* OpenGLES 2.0 support on PLATFORM_DESKTOP

* exmples raylib_opengl_interop desktop GLES2 support

* rename gles2.h -> glad_gles2.h

It directly uses the libraries provided by the system

Note this new raygui version embeds ricons and `GuiTextBoxMulti()` is not working properly
