We are currently representing type variables using a `KnownInstance` variant, which wraps a `TypeVarInstance` that contains the information about the typevar (name, bounds, constraints, default type). We were previously only constructing that type for PEP 695 typevars. This PR constructs that type for legacy typevars as well. It also detects functions that are generic because they use legacy typevars in their parameter list. With the existing logic for inferring specializations of function calls (#17301), that means that we are correctly detecting that the definition of `reveal_type` in the typeshed is generic, and inferring the correct specialization of `_T` for each call site. This does not yet handle legacy generic classes; that will come in a follow-on PR. |

Ruff Benchmarks
The ruff_benchmark crate benchmarks the linter and the formatter on individual files:
# Run once on the "baseline".
cargo bench -p ruff_benchmark -- --save-baseline=main
# Compare against the "baseline".
cargo bench -p ruff_benchmark -- --baseline=main
# Run the lexer benchmarks.
cargo bench -p ruff_benchmark lexer -- --baseline=main
See CONTRIBUTING.md on how to use these benchmarks.
