Introduce a ruff_python_semantic crate

[charliermarsh]

Summary

This PR moves the following modules into a new ruff_python_semantic crate, to separate non-semantic AST responsibilities (call_path.rs, newlines.rs, etc.) from the semantic model, which will be captured in this crate:

• binding.rs
• scope.rs
• context.rs

There are a few additional modules that were in ruff_python_ast and depend on Context, but aren't part of the "semantic model" per se. For example, visibility.rs determines the visibility (public, private) of a given binding, and also has utilities for checking whether the declaration is abstract, static, etc. None of this is captured by the AST, so it requires semantic analysis. For now, I included these under ruff_python_semantic::analyze.

These are just definitions of types in the standard library, so they belong in ruff_python_stdlib.
