Include vertical alignment options in Cover and Columns block

[enriquesanchez]

It'd be great if more blocks such as 'Cover' and 'Columns' had the same vertical alignment features that are found in the 'Media & Text' block:

This feature, if also applied to text child blocks, will allow for more control over text layout and alignment.

See #20900 for a comparison between what was intended and what was actually possible with Gutenberg.

I have this feature added on EditorsKit plugin few months ago and here's the preview on how I've implemented the vertical alignment on Cover Block. I used verticalAlignment attribute similar to what Columns block is using. Thanks!

Thanks for sharing the method you used for Editor's Kit, Jeffrey! I am thinking we could perhaps do something similar for Gutenberg Core Cover Block. I do believe these days there are an overhaul of the various alignment options happening. To figure out how to better represent these in the toolbar.

Thank for the feedback and examples @phpbits and @paaljoachim!

I'm closing this issue in favor of #20836, which is addressing the same topic and already has some design explorations.
