Image and post featured image are missing border style control

[carolinan]

Description

The image and featured image block has block support for border color, radius and width.
The missing border style control causes problems for themes that has a border style that is more specific than the CSS that is output by the block library:

html :where([style*=border-width]) {
    border-style: solid;
}

This can cause the border to not be visible.

Before I work on this, I am trying to understand why the border style was omitted.
@aaronrobertshaw -I have read through #42847 but it is still unclear to me:
Does the placeholder border break if the border style option is added?

Thanks for the ping @carolinan 👍

You might find extra context and history in the PR adding border support to the Image block. The supports adopted for the Post Featured Image block were chosen so they were consistent.

I'm currently at the end of my day here and will be AFK tomorrow. I'll dig a little deeper into the history and possible options on Friday.

Edit: Here's where the decision to omit border style was initially made - #31366 (comment). Perhaps with recent advancements to the block selectors API we might be nearing a time to revisit that call.
