Move breadcrumbs out of location picker heading

[LukasHirt]

Description

We've moved the breadcrumbs element out of the location picker heading and moved it under it.
The heading is now also reflecting the page title.
We've also decreased the size of both breadcrumbs and action buttons so that they fit better together.

I'm trying to think about the table... it has different padding than anything above it. Updating ODS with prop for padding of the table would again just increase the effort & time needed but I do not want to decrease the padding from elements above as that looks like 💩

There's more - the horizontal line above has a slight margin left and right, while the borders of the table go from left to right without margin. Could you check if applying that same margin to the left and right of the table makes it look better? If not, then I'd be all in for making the padding left and right slightly bigger in the ODS component.

In the All files view we now have the variation="lead"for the breadcrumbs. Could you check if you can use the same here? I think that the variation="lead" has a font size that it too big for the use case. Would prefer something in the middle. Smaller than lead and bigger than regular. Maybe introduce a third option?

@kulmann I would say it's ready for review. We need an ODS update for the padding improvement, but we do not need to touch anything after that so I wouldn't really block this PR because of that.
