This patch: * allows for heap and perf profiling of all processes on the system (minus undumpable and otherwise incompatible domains). For apps, the rest of the platform will still perform checks based on profileable/debuggable manifest flags. For native processes, the profilers will check that the process runs as an allowlisted UID. * allows for all apps (=appdomain) to act as perfetto tracing data writers (=perfetto_producer) for the ART java heap graph plugin (perfetto_hprof). * allows for system_server to act a perfetto_producer for java heap graphs. Bug: 247858731 Change-Id: I792ec1812d94b4fa9a8688ed74f2f62f6a7f33a6
