Allow setting margins for embeds

[carolinan]

What problem does this address?

If you want a design with some additional top and/or bottom spacing around embeds, for example a Youtube video,
you need to add spacing blocks or place the embed inside a container, and add the spacing to the container.

What is your proposed solution?

Enable top and bottom margin controls for embeds and the video block.

The reason why I am suggesting top and bottom margin only is that I am assuming that if you are aligning multiple videos horizontally, you are more likely to already be using a column or row as a container, and you would use the container block gap to space the items.

Hi @carolinan, Thank you for this suggestion, I think we can also add the left and right margin if someone wants to add the embedded block without any column or container.

In terms of left/right margins, I have a case in the forums where text wrapping around a right-aligned Youtube embed goes right up to the edge of the embed. This enhancement should help prevent this type issue.

Hi @KokkieH, Thank you for the reference that's really helpful. I agree with your point, that allowing the left/right margin to be controlled will help the user to remove this kind of issue.
