[1.8.x] 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.
Backport of 78d43a5e1064b63db1c486516c4263ef1c4c975c from master
