feat(core): Remove storeMetadata and getSize from binary data manager interface (no-changelog) (#7195)

Depends on: #7164 | Story:
[PAY-838](https://linear.app/n8n/issue/PAY-838/introduce-object-store-service-for-binary-data)

This PR removes `storeMetadata` and `getSize` from the binary data
manager interface, as these are specific to filesystem mode. Also this
disambiguates identifiers:

```
binaryDataId
filesystem:289b4aac51e-dac6-4167-b793-6d5c415e2b47 {mode}:{fileId}

fileId - FS
289b4aac51e-dac6-4167-b793-6d5c415e2b47 {executionId}{uuid}

fileId - S3
/workflows/{workflowId}/executions/{executionId}/binary_data/b4aac51e-dac6-4167-b793-6d5c415e2b47
```

Note: The object store changes originally in this PR were extracted out
into the final PR.
