/// @brief Collect contents of specified trace array via SCOM.
///
/// Collects contents of specified trace array via SCOM. Optionally
/// manages chiplet domain trace engine state (start/stop/reset) around
/// trace array data collection. Trace array data can be collected only
/// when its controlling chiplet trace engine is stopped.
///
/// Trace array entries will be packed into data buffer from
/// oldest->youngest entry.
///
/// Calling code is expected to pass the proper target type based on the
/// desired trace resource; a convenience function is provided to find out
/// the expected target type for a given trace resource.
