Improvement: Add tracing for subscription-states

[crimson11]

What

The following proxy side trace-points (see score/mw/com/impl/tracing/configuration/comtrace_config_schema.json) are currently not yet implemented:

• trace_subscription_state_changed
• trace_subscription_state_change_handler_registered
• trace_subscription_state_change_handler_deregistered
• trace_subscription_state_change_handler_callback

the underlying API entry-points all exists/are implemented, so no reason, not to implement these trace-points.

How

All these trace-points can now be implemented.
trace_subscription_state_changed and trace_subscription_state_change_handler_callback shall (additiojnally to the stadard meta-info) provide as - chunk list: value new subscription state (8 bit value)

Estimates for realization

2 weeks
