[Android] Add ProjectM (ported MilkDrop) Music Visualization

Currently the Andriod [ARM] Kodi only comes with the Spectrum visualization, which is very bland in comparison to ProjectM / MilkDrop.

ProjectM is an is an implementation of MilkDrop supporting OpenGL, and in 2011 it was ported to OpenGL ES 2 for ARM, and released under the GNU LGPL. There is currently only a stand-alone version of ProjectM available for Android.

While Windows and Linux versions of Kodi support the visualization.projectm , it has never been ported to gles on the Kodi side. I’m told that the library supports it however, so it’s “just” some glue missing to make it work for ARM environments.

I therefore humbly request this feature for Kodi Krypton.
