Dreport: Add D-Bus Statistics Collection
Add functionality to collect statistical information about
D-Bus usage as part of the debug data collection process.
Including this information in debug reports will enhance
troubleshooting capabilities for D-Bus related issues in
OpenBMC-based systems. It provides a snapshot of D-Bus
activity and performance at the time of report generation.
This addition will help identify potential communication
bottlenecks, unexpected service behaviors, and performance
issues related to inter-process communication, system
management interfaces, and sensor data retrieval.
Tested on qemuarm.

High OutgoingBytes:
While all connections show 0 in the given data, a connection
with consistently high OutgoingBytes might suggest a blocked
receiver or network issues.
Rapidly Increasing NameObjects:
If a connection's NameObjects count grows quickly over time,
it may indicate a resource leak.
Mismatched IncomingBytes and OutgoingBytes:
Large discrepancies between these values across multiple
connections could suggest communication issues.
High Number of Connections:
An unusually high number of active connections
(the log shows 33) might indicate connection leaks
or denial-of-service attempts.
