Error type for wasi:http embedder interactions.

This error type is a superset of the wasip2/wasip3 error types for example and is the error that the embedder interacts with for all operations.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
