  Log Message:
  -----------
  [mlir] Update the use-list algorithms in SymbolTable to support nested references.

Summary: This updates the use list algorithms to support querying from a specific symbol, allowing for the collection and detection of nested references. This works by walking the parent "symbol scopes" and applying the existing algorithm at each level.
