Marcin Zawiejski bd5ff205b2 Revert "Batch GLES2 draw calls" 
This reverts commit f55039b194.

The GLES2 batching seems to require more testing and tweaking in order
to actually make the performance better on Android devices. It's been
proved with #21184 that the current implementation has it's drawbacks
therefore I suggest reverting the commit for now.
