## 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.
