This PR can be merged long ago, not sure if any of the requested changes still hold today considering everything is mathematically sized to Android recommended grid. (Although my opinion is we shouldn't follow the grid at all because the grid assumed the icon is mostly square/circle shape and not elongated triangle)

I remember I had issues with the PR, so I'll review it before merging

There's no reason to use density defined resolutions, we already have a much better way in mipmap-anyapi, Android will scale down/up as needed automatically.
