Initial attempt at CA-based PRWConfig_tf.py (ATLASG-2969)
In ATLASG-2969 it was noted that running PRWConfig_tf.pyin Athena-23.0.20 on AODs produced in Athena-24.0.88 does not work.
However running PRWConfig_tf.pyin Athena-24.0.X is not possible as the legacy configuration it used was removed in !70258 (merged)
This merge request attempts to add a ComponentAccumulator-based skeleton for PRWConfig_tf.py, so that it can be used in future 24.0.X releases.
