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.
