Initial content scanner integration (#7139)

* Create a `ContentScanner` component:

- Add `:features:contentscanner:api` module with the interface.
- Implement the concrete component using the Rust SDK in `:libraries:matrix:impl`.

This can be used to both set up the content scanner media fetching in the SDK Client and manually scanning media sources from the Android side

* Create `ContentScannerUrlProvider` in a new `:features:contentscaner:api` module as a noop implementation

Use it as a placeholder for the code to instantiate a `RustContentScanner` with the fetched URL and set it as part of the SDK client.

* Expose the optional `ContentScanner` in the `@SessionScope`

* Split the storage part of the Element well-known retriever so it can be reused for the non-session bound retriever.

Also add the new `content_scanner_url` field to it.

This will be used by the enterprise code to fetch the actual content scanner url.

* Bump enterprise commit to have access to the actual content scanner url provider implementation

* Fix tests and lint issues

* Use the right namespace for `:features:contentscanner:api`, also use the right namespace for `impl`
