In every European country, there's a legal requirement to give notice. And therefore there is an incentive for the company to maintain amicable relations during the notice period to try and prevent trouble.

How do they proceed operating after kicking people out without prior notice? Do those projects just get stomped and started over with new people?
That doesn't follow at all. The notice period exists so you can transfer your knowledge and projects to colleagues who will take over your work.
If the notice period is in the company interest when people leave on their own, it's also in the company's interest when they have to leave?
It is both in the interest of the company and employee, as neither can terminate the contract immediately.
So it's virtually unheard of to show up, hear about layoffs, and not have a job the next day. Unless it's a situation where the whole company is going bankrupt or so.
Required or allowed? So in the US you can't give notice?
It is probably better phrased as “In the US, notice is not legally required”.
I imagine most of the time people will have the courtesy of giving 1-2 weeks notice if possible.
That said, sometimes the company will decide that they'd rather you just go, and they'll tell you not to bother giving notice and you can leave immediately. Someone in another comment said that was because of bad blood, but it's also because of risk and it's unlikely that a person will be very productive during a short notice period.
When there's a tricky hand-off, though, the company might ask for and incentivize a longer notice period, too... So nothing's written in stone.
