Previously, we had read-utf8 and write-utf8 instructions. The latest version of the standard proposes respectively memory-to-string and string-to-memory. The semantics is close though.

1284: feat(interface-types) Implement string and memory instructions r=Hywan a=Hywan

Previously, we had `read-utf8` and `write-utf8` instructions. The latest version of the standard proposes respectively `memory-to-string` and `string-to-memory`. The semantics is close though.

This PR was included in a batch that successfully built, but then failed to merge into master (it was a non-fast-forward update). It will be automatically retried.

1285: feat(interface-types) Greatly improve errors r=Hywan a=Hywan

~This PR is build on top of #1284. It must be merged first. [View the exact diff](https://github.com/Hywan/wasmer/compare/feat-interface-types-instructions-string-and-memory...Hywan:feat-interface-types-better-error?expand=1).~

Errors in `wasmer-interface-types` were just `&'static str`, which isn't quite great 😉. This PR introduces the `errors` module, with structures that represent errors. A `Display` implementation maps the errors to strings.
