SWDEV-351980 - Enable profiling for commands reporting activities

Profiling should be enabled for any command reporting activities as the
activity record captures the profilingInfo's start and end timestamps.

Since IS_PROFILER_ON is only used to determine whether API tracing is
enabled, there is no need to expose it globally, it should be a property
of the activity_prof::CallbacksTable.
