[Enhancement]: Add support to store images/attachments in GCS (without firestore)

[goreply-de]

What features would you like to see added?

An option to store images and assets in Google Cloud Storage without the need of firestore.

More details

It would be nice if a user can configure where images should be stored. Currently they are stored in firestore or local, but GCS would be a valid alternative that can save costs.
Changes that need to be done (for a public GCS bucket):

• The data-provider needs to support gcs as FileSources enum
• A new service needs to be added: api → server → services → Files → GCS
• A GCS strategy needs to be added (see api → server → services → Files → strategies.js and process.js)
• For images with GCS the encoder needs to be extended (see api → server → services → Files → images → encode.js)

If the user can select the storage, the UI should allow this decision.
