[exporter/datadog] Expose source provider (open-telemetry#37668)

#### Description

The goal of this PR is to expose the `GetSourceProvider` method from
hostmetadata, which is currently under an internal folder in
datadogexporter.

In order to do so, we create new package
`github.com/open-telemetry/opentelemetry-collector-contrib/pkg/datadog/hostmetadata`
which calls on internal hostmetadata's `GetSourceProvider`.

We also create new module
`github.com/open-telemetry/opentelemetry-collector-contrib/internal/datadog`,
where we store the internal `hostmetadata`, `clientutil` and `scrub`
packages. We move `hostmetadata` there as it needs to be imported in
both datadogexporter, and `pkg/datadog/hostmetadata`, and we move
`clientutil` and `scrub` there as they are imported by `hostmetadata`.
