Add `GetStepTools<typeof inngest>` type for getting generic tooling type

[jpwilliams]

Summary

Adds a GetStepTools helper type to go alongside GetEvents to provide users with a way of accessing some of the internal types provided by Inngest.

type StepTools = GetStepTools<typeof inngest>;
type StepToolsWithTrigger = GetStepTools<typeof inngest, "app/user.created">;

Also provides GetFunctionInput to get all input arguments for an Inngest function.

type FunctionInput = GetFunctionInput<typeof inngest>;
type FunctionInputWithTrigger = GetFunctionInput<typeof inngest, "app/user.created">;

These complement the existing GetEvents type available.

type Events = GetEvents<typeof inngest>;

Both types include middleware in the result.
