There are still some left in the Android Java code, even stuff to swap between GLES1 and GLES2 support from early Godot days... would be good to see some cleanup there too one day. The "graphics/api" option for Android exports is removed, as only GLES 3.0 is supported. It can be readded when GLES 2.0 support comes back. Fixes #13004.
