feat: wasmer-config

Add a new wasmer-config create, which:

* Supersedes the wasmer-toml crate
* Includes the app.yaml configuration schema

Compared to the original upstream wasmer-toml, this PR includes the
following additions:

* new types for packages (PackageSource, PackageId, PackageIdent,
  Sha256Hash, PackageHash, ...)
* `AppConfigV1`, which describes the format of `app.yaml` files

The motivation for inclusion is to:

* Simplify management so we don't have to maintain another repository
* Expand the scope of the crate to include additional Wasmer related
  configuration - we would oterhwise need to maintain additional crates

The PR also adds a new Github workflow for checking the crate.
