[AND-176] Intercept Attachment Download Process within internal activities

[JcMinarro]

🎯 Goal

Related PR: #5490

On implementing the previous PR, the use of DownloadAttachmentUriGenerator and DownloadRequestInterceptor was obtained from the ones configured within ChatTheme entity.
The problem is that our internal activities don't use the ChatTheme that our customers configure when they initialize the SDK. There aren't any static references to it, so the default implementation was used.

With this PR the customization used on ChatTheme is forwarded to our internal activities

🧪 Testing

To test it, you only need to add a custom implementation of those dependencies and check it is being used when downloading attachments.

Patch that prints some logs when the implementation is used
