Log Message:
-----------
Print compositor execution statistics when in background mode

This will print memory usage, mapped memory usage, memory peak,
compositing tree name and number of finished tiles to stdout
when blender is rendering in background mode.

This makes compositor a less blackbox and should help trouble
shooting issues happening during 4K ToS project.
