Gallery block - semi cross platform approach

[pinarol]

We can still have single edit.js and share @wordpress/components imports with web. But since we don't have an approved approach for replacing the web elements yet let's re-think about x-platform tiles, image subtasks. Especially if we think we won't be able to use the x-platform image component without the rest of the primitives let's re-think about the ideal next steps.

This issue is just for documenting the next steps, doesn't mean that we'll track the whole work with this, we should create new development subtasks if needed.

Some steps:

• Make sure it works with existing content (i.e. open a post that was created on web)
• Choosing media from WordPress Media Library
• Choosing media from device (i.e. uploading media) tracked here: Mobile gallery block - Upload options #1610
