Ensure R8 mapping file provide sufficient information for retrace

* Always run line number optimization to collect line numbers and
  inline frame information. For debug mode stick to the identity
  line mapping for now

* Fix line number optimization for the identity mapping

* Skip emitting destination line range of equal to the source
  line range

* Add an initial simple test for using the generated mapping file
  with Proguard retrace

This removed the distinction between line number
optimization "identity" vs "off". Now there is only on and off.
