Graph - (tiny) performance improvements (#6382)
* Fix revert if adding a node failed.

* Reduce allocations by keeping only a single RzGraphEdge object per edge around.

* Add benchmark for graph deletion and addition of nodes/edges

* Use rz_pvector_remove_at_unsorted to save some runtime.

* Use realloc and memmove for matrix graphs on capacity increase.

* Add helper to determine memory usage.

* Add benchmark

* Revert matrix capacity extension to simple and jsut as fast loop.

* Missing type annotations

librz/util/graph: various improvements
* GRAPH: Add rz_graph_add_get_node() and refine API.
* GRAPH: Remove unused, and rename parameters.
* Improve doxygen.
* Implement rz_graph_del_edges()
* Rename rz_graph_node_get_hash_id() to rz_graph_node_get_hash_id() to make clear what identifier is returned.
* Simplify node identification.

Removes the option to have two sources of identifiers (node data or other identifier data).
Changes the API to use the hash id instead of a pointer to data.

* Fix type annotations.
* Remove duplicate function.
* Fix invalid asserts.
* Set flag if node was present.
* Grow by a factor of 1.25. Exponential growth quickly leads to OOM.
* Remove the edge index again to not remove reduce the main advantage of an adjacency matrix
* Refactor list based graph to use vectors instead of hash maps for edges.
* Fix heap-use-after-free
* Add an rz_graph_update_edge function.
* Add function to print graph as dot graph.
* Add warning about del_edges runtime.
* Refactor add_node to use RzGraphStatus.
* Refactor del_node to use RzGraphStatus.
* Use cast-macro to prevent ASAN issues.
