Rémi Verschelde 9f134aa5d1 Cleanup old references to GLES2 renderer
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.
