Twenty Twelve: Add Block Patterns

[melchoyce]

With block patterns introduced in WordPress 5.5, we now have the opportunity to add some patterns to our older default themes.

Let's consider adding some patterns to Twenty Twelve.

With Beta 1 for 5.6 landing in less than 2 weeks, punting this ticket to Future Release. If any maintainer or committer feels this can be resolved in time, or wishes to assume ownership during a specific cycle, feel free to update the milestone accordingly.

I have designed some more block patterns for Twenty Twelve.

Those are great @beafialho! I like the floating images one especially.

Do you have a preference between the two quotes ones? They're both so similar that I think we should include just one of them.

Thanks @kjellr! I like them both but I believe the left-aligned quote with no background may work better for this theme.

I'm going to move this to 5.8. But, if they are ready sooner we can move this to 5.7.1 (or if that's not realistic, please do move this back Future Release).

We can also release an update detached from a specific WordPress release as we ​did in December.
