perf cs-etm: Add warnings for missing DSOs
Currently decode will silently fail if no binary data is available for the decode. This is made worse if only partial data is available because the decode will appear to work, but any trace from that missing DSO will silently not be generated. Add a UI popup once if there is any data missing, and then warn in the bottom left for each individual DSO that's missing.
