Feature request: improve generic types of Idempotency utility

[dreamorosi]

Use case

The current version of the Idempotency utility uses generic types to allow for unknown payloads and function types. The types however are overly broad and use any.

We should dedicate time to improve them and narrow them down ahead of the GA release.

Solution/User Experience

TBD, however the new types should support all the types of payloads that the utility support while disallowing payload types that would cause runtime errors.

Alternative solutions
