Vladimir Sementsov-Ogievskiy b83a80e831 meson: generate trace events for qmp commands
1. Use --gen-trace when generate qmp commands
2. Add corresponding .trace-events files as outputs in qapi_files
   custom target
3. Define global qapi_trace_events list of .trace-events file targets,
   to fill in trace/qapi.build and to use in trace/meson.build
4. In trace/meson.build use the new array as an additional source of
   .trace_events files to be processed
