Dhruv Manilawala bd4a947b29 [red-knot] Add symbol and definition for parameters (#12862 )

## Summary

This PR adds support for adding symbols and definitions for function and
lambda parameters to the semantic index.

### Notes

* The default expression of a parameter is evaluated in the enclosing
scope (not the type parameter or function scope).
* The annotation expression of a parameter is evaluated in the type
parameter scope if they're present other in the enclosing scope.
* The symbols and definitions are added in the function parameter scope.

### Type Inference

There are two definitions `Parameter` and `ParameterWithDefault` and
their respective `*_definition` methods on the type inference builder.
These methods are preferred and are re-used when checking from a
different region.

## Test Plan

Add test case for validating that the parameters are defined in the
function / lambda scope.

### Benchmark update

Validated the difference in diagnostics for benchmark code between
`main` and this branch. All of them are either directly or indirectly
referencing one of the function parameters. The diff is in the PR description.

Vendored types for the stdlib

This crate vendors typeshed's stubs for the standard library. The vendored stubs can be found in crates/red_knot_python_semantic/vendor/typeshed. The file crates/red_knot_python_semantic/vendor/typeshed/source_commit.txt tells you the typeshed commit that our vendored stdlib stubs currently correspond to.

The typeshed stubs are updated every two weeks via an automated PR using the sync_typeshed.yaml workflow in the .github/workflows directory. This workflow can also be triggered at any time via workflow dispatch.
