Should EuiPage be a main element?

[myasonik]

Does it make sense for EuiPage or EuiPageBody to be a <main> element?

Going through Kibana, most pages are missing a main element wich automated tools often yell about so we often hear about it when customers do their own audits.

If y'all want to keep EuiPage and friends free of semantics that's fair enough and we can push adding main elements to Kibana devs but it seemed like a good place.

I think it makes sense for Page body. We might want to have the element it uses as a prop, which defaults to main. I'm guessing a couple places use it multiple times in a layout.
