feat!: add support for secrets in manifests

This adds support for secrets in wasmCloud application manifests. The
secrets themselves are actually _secret references_ as outlined in
wasmCloud/wasmCloud#2190. Just like config, secrets can be specified at
the component or provider level or on a link.

Secret references themselves are actually implemented as an additional
kind of config stored in the same config data bucket. However, I opted
to implement a dedicated scaler for secrets that is largely a clone of
the existing ConfigScaler since the underlying data type is very
different than the arbitrary set of key/value pairs we use for config.

An example of what this looks like in a component is shown below:

```yaml
spec:
  components:
    - name: http-component
      type: component
      properties:
        image: ghcr.io/wasmcloud/test-fetch-with-token:0.1.0-fake
        secrets:
          - name: some-api-token
            source:
              backend: nats-kv
              key: test-value
              version: 1
          - name: my-other-secret
            source:
              backend: aws-secrets-manager
              value: secret-name
              version: "be01a5fb-7ebb-4ae9-8ea0-0902e8940bc0"
```

This contains a breaking change to the way that we specify config on
links:

```yaml
- type: link
  properties:
    namespace: wasmcloud
    package: postgres
    interfaces: [managed-query]
    target:
      name: sql-postgres
      secrets:
        - name: db-password
          source:
            backend: nats-kv
            key: myapp_db-password
            version: 1
```

Instead of using `target_config` and `source_config`, this renames them
to `target` and `source` respectively and adds keys for `config` and
`secrets`. The name of the target is now now a key at the top level of
the `target` block, as seen above.
