Post Comments Form Block: Block should ship with default styles

[kjellr]

The post comments form block currently renders completely unstyled:

This should ship with a set of default styles so it can be used out of the box in block-based themes.

One wishlist item for this: The button block should inherit the standard wp-block-button styles.

Ideally, it would be an actual nested (variation of a) button block, so that users could modify its appearance.

@kjellr I took a little time in mocking this up and will spin up a PR to get iterations going as hopefully most can be done in CSS (yet to confirm that).

Suggestion

I went really simple using the grid variables for spacing and default scale for typography. This should also allow easier customization of this in the future.

Relating to customizing, here is what coloring that slightly could for example lead to, this could just be done using variable changes:

I did noticed that the placeholder for the post comments form is also a little sparce, so opened an issue #26999.

Feedback

I'm looking for any feedback, but specifically is this giving the flexibility needed along with tidying up?

This seems like a good start, thanks @karmatosed!
