Closes #27073

Currently, when searching for a file with Ctrl+P, and the first file
found is the active one, file_finder skips focus to the second file
automatically. This PR adds a setting to disable this and make the first
file always the focused one.

Default setting is still skipping the active file.

Release Notes: 

- Added the `skip_focus_for_active_in_search` setting for the file
finder, which allows turning off the default behavior of skipping focus
on the active file while searching in the file finder.
