Several common DefinitionKind variants retain separate references to child AST nodes even though their parent node already retains those children. Lambda parameter definitions also retain a usize index.
Retain parent nodes for annotated assignments, import-from submodules, for statements, comprehensions, and with items, recovering their child nodes through the parent when needed. Store lambda parameter indices as u32.
On oaiproto, this reduces retained memory by 1,175,760 bytes (0.289%).
