SQL/PGQ or even GQL support

### Is your feature request related to a problem or challenge?

SQL (standard) was recently extended with property graph querying features (PGQ): [ISO standard](https://www.iso.org/standard/79473.html), [theoretical foundations](https://arxiv.org/abs/2409.01102). I wonder if DataFusion can be extended with PGQ.

### Describe the solution you'd like

All parts should be extended. The most nontrivial part is interconnection between traditional SQL and graph analysis (path-related evaluations). While it is possible to store graph in columnar storage (e.g. Apache Arrow), it may be inefficient for path-related queries (while pretty efficient for attributes-of-vertex-related analytical queries). So, specific path-indexes may be required. Even more, in some cases it may be good idea to store graph topology in separated storage in specific format (e.g. sparse adjacency matrix, similar to [FalkorDB](https://docs.falkordb.com/design/#the-theory-ideas-behind-falkordb)).
On the other hand, even if we store graph in columnar storage, linear-algebra-related primitives can be useful for path querying ([DuckPGQ: Efficient Property Graph Queries in an analytical RDBMS](https://www.google.com/url?sa=t&source=web&rct=j&opi=89978449&url=https://www.cidrdb.org/cidr2023/papers/p66-wolde.pdf&ved=2ahUKEwiw3On90PSJAxVpIhAIHZLeCnQQFnoECBcQAQ&usg=AOvVaw3a0YNXq5JLEWEJ4lNRAKdk)).

So, logical and physical plans should provide not only specific operators, but support balancing between data representation.

### Additional context

Can something like [this project](https://github.com/code-sam/graphblas_sparse_linear_algebra) be used for physical level of linear algebra?

[Possible theoretical foundations](https://www.irif.fr/~rogova/thesis_Alexandra_Rogova.pdf).

It may be a first step to support [GQL](https://www.iso.org/standard/76120.html).

I'm interested in such a system design and development, but I'm aware that such an extension of DataFusion may leads to system recreation. So, I want to discuss this direction: should we extend DataFusion or create new independent system.

No implementation files, tests, or entry points are identified. Start by reviewing the proposed PGQ/GQL scope and discussing whether DataFusion or a separate system should own it; done requires an agreed design and initial implementation plan.
