Latest posts: consider to don't list the post where the block is used

[afercia]

When inserting a "Latest posts" block in a post, it displays also the "host" post if it's recent enough:

This doesn't seem particularly useful. While the classic Recent Posts widget is typically used in a sidebar and thus it's correct it displays all the recent posts, the Latest Posts block (aside: why it has a different name: Recent vs. Latest?) is used in the post content and should exclude the "host" post when this is in the recent ones.

Additionally, when inserting the Latest Posts block in Gutenberg:

• create a new post
• don't save the post yet
• insert a Latest Posts block
• the "host" post is not included (because it's still a draft):

• save
• refresh the page
• now the host posts is listed

This mix of different behaviors can be confusing for users and should probably be improved a bit.

If we were to add this feature, we should consider the fact that this block could be used in a page or a site builder later (the same block) and there's no host post.

I think the way forward here is to support some or all of the REST API's query parameters and automatically include ?exclude=ID for the current post ID.

To me this sounds like a perfect toggle to have in Block Settings.

Something like:

Omit most recent post       [ on/off ]

?

Let's close this one for now. It could be something we add later but that would be after phase one. It may also be something people extend.
