Refs #24366 -- Fixed recursion depth error in migration graph

iterative approach in case the recursive approach exceeds the recursion
depth limit.

Fixed #24366 -- Optimized traversal of large migration dependency graphs.
...
Switched from an adjancency list and uncached, iterative depth-first
search to a Node-based design with direct parent/child links and a
cached, recursive depth-first search. With this change, calculating
a migration plan for a large graph takes several seconds instead of
several hours.
Marked test `migrations.test_graph.GraphTests.test_dfs` as an expected
failure due to reaching the maximum recursion depth.

Fixed bug in circular dependency algo for migration dependencies.
...
Previous algo only worked if the first item was a part of the loop,
and you would get an infinite loop otherwise (see test).
To fix this, it was much easier to do a pre-pass.
A bonus is that you now get an error message that actually helps you debug
the dependency problem.
