Validates that the keys in the provided input are valid for at least one action on the resource.
Raises a KeyError error at compile time if not. This exists because generally a struct should only ever
be created by Ash as a result of a successful action. You should not be creating records manually in code,
e.g `%MyResource{value: 1, value: 2}`. Generally that is fine, but often with embedded resources it is nice
to be able to validate the keys that are being provided, e.g
```elixir
Resource
