Use OpenGL 3.3 core profile instead of compatibility profile

- Rename OpenGL to GLES3 in the source code per community feedback. - The renderer is still exposed as "OpenGL 3" to the user. - Hide renderer selection dropdown until OpenGL support is more mature. - The renderer can still be changed in the Project Settings or using the `--rendering-driver opengl` command line argument. - Remove commented out exporter code. - Remove some OpenGL/DisplayServer-related debugging prints.
