Render engines: replace number of x/y tiles with tile size

Now tile size is setting up explicitly instead of using number of tiles.

This allows better control over GPU performance, where having tiles aligned
to specific size makes lots of sense.

Still to come: need to update startup.blend  to make tiles size 64x64.
