Fix rocprofiler plugin

- Replace non-working fields with working ones
    - remove CU_OCCUPANCY completely as it isn't well supported
- Fix rocprofiler initialization with shared_ptr and rdc_module_init
- Replace env var ROCPROFILER_METRICS_PATH with ROCP_METRICS
    - ROCPROFILER_METRICS_PATH is only relevant for rocprofv2
    - ROCP_METRICS is only relevant for rocprofv1 (which we are using)
