[rocprofiler-compute] Fix for multi process workload profiling (#2418)

* Fix for multi process workload profiling

Native counter collection tool updates:
    * Do not dump empty counter data for a process
    * Use PID instead of UUID for dumped csv files to facilitate correlation
    * Handle merging multiple pairs of rocpd (from sdk tool) and csv (from
      native tool) files
    * Handle merging multiple pairs of csv (from sdk tool) and csv (from
      native tool) files

Rocpd output format updates:
    * Merge multiple rocpd databases into a single csv
    * Reset dispatch id and kernel id for unique dispatches and unique
      kernels respectively
    * Retain multiple rocpd databases per run for multi process workloads

* Add test case for multiprocess profiling using rocflop workload

* Add rocflop

* Fix native counter csv to rocprofv3 csv conversion

* Use kernel_id instead of dispatch_id to correlate native counter csv
  and kernel trace csv

* python formatting using ruff 0.14 instead of 0.13
