This task is part of gsoc for "Modernize backend and improve developer experience" since one of our core goals for 3.26 (and backport to 3.24) is iron out the search use case of type-ahead.

files-view: Select file after "Open item location"

Until now we weren't selecting the item that was selected.
However it really helps to do that so the user can navigate after
searching. For instance this is pretty good to have for the "type-ahead"
use case.

This commit select the file after the user opens the item location
and reveals the file.

It was missing in the new GtkFlowBox based view.

files-view: Reveal file in an idle for the flow view

Items are not allocated at that time yet, so it needs some time to be
able to calculate the correct allocation of the item, and therefore the
correct adjustment for the scrolled window.
