Enable offline generation of text-based symbol tables for native images. This is needed in order to profile applications on Linux using perf_event.
This change also modifies the runtime to emit a perfmap entry when a native image is loaded so that offline trace processing tools can identify when a perfmap file for a native image is needed and generate it.
