This implements an interface that export the names of the plan nodes and functions that need to be counted in the metrics.
Also, the metrics are now counted from within the parser. This should allow correct accounting for the cases where some nodes can appear both standalone or part other nodes' children (like Aggregate being a child of INLINESTATS, so no STATS counting should occur).
The functions counting now also validates that behind a name there is actually a function registered.
Closes #115992.
