[SYSTEMDS-3710] Function entry/exit marker in lineage traces

This patch adds a new utility in lineage tracing for debugging and
interpretability. The flat lineage tracing makes it harder to track
calls to built-ins and the arguments (e.g. hyperparameters). To better
structure the lineage traces, we now add function start end markers
for each input and output, respectively. These entries are NOOPs and
do not impact the reuse in any way.
Future tasks include adding similar markers for control flow and
enable deserialization of these markers.
Note, this utility is default disabled and can be enabled using the
flag, LineageItemUtils.FUNCTION_DEBUGGING.

Apache SystemDS

Overview: SystemDS is an open source ML system for the end-to-end data science lifecycle from data integration, cleaning, and feature engineering, over efficient, local and distributed ML model training, to deployment and serving. To this end, we aim to provide a stack of declarative languages with R-like syntax for (1) the different tasks of the data-science lifecycle, and (2) users with different expertise. These high-level scripts are compiled into hybrid execution plans of local, in-memory CPU and GPU operations, as well as distributed operations on Apache Spark. In contrast to existing systems - that either provide homogeneous tensors or 2D Datasets - and in order to serve the entire data science lifecycle, the underlying data model are DataTensors, i.e., tensors (multi-dimensional arrays) whose first dimension may have a heterogeneous and nested schema.
