Reduce starlark boilerplate with eldritch wrappers

[hulto]

Implementing modules, functions, and types in eldritch requires a lot of boilerplate.
Boilerplate isn't necessarily bad but we're starting to have a lot of it (especially with the new eldritch-types branch). Reducing the starlark boilerplate should: improve test coverage by line, make future refactor like when updating starlark easier, and improve our code bases readability.

How can we reduce this boiler plate?

• can we implement parent types like EdlritchModule, EldritchFunction, and EldritchType. These types would implement the functions required by starlark like StarlarkValue and UnpackValue in the parent type.
