Olivero should style Views exposed filters as inline (currently are stacked)

I like the idea of adding specific .form--inline styles. I wasn't initially considering it, but it makes sense.

I'm attaching an updated patch that adds that class directly onto the Views exposed filters form, and I'm also using display: inline-block to handle the inline elements instead of float. This will handle RTL a bit better, and is more what we're trying to do.

Last test failure is unrelated.

How do we expect this to look when the form element has a description?

Not like that!

Fix attached!
