Move Ranged into ruff_text_size (#6919)

## Summary

The motivation here is that this enables us to implement `Ranged` in
crates that don't depend on `ruff_python_ast`.

Largely a mechanical refactor with a lot of regex, Clippy help, and
manual fixups.

## Test Plan

`cargo test`

crates/ruff_python_semantic/src/nodes.rs
