Emscripten: remove GLES_DeleteContext implementation

It was calling glClear without a context. The issue it was trying to
solve was actually that after destroying a window and creating a new one
, the contents of the old window were preserved. This no longer happens
since we resize the window to nothing on destroy.

WebGL contexts can't actually be deleted, so we need to reset it.
ES2 renderer resets state on init anyway, clearing the canvas should be enough
