Subject: feat: add hide / unhide preview (#1305)

* feat: add hide / unhide preview or results and prompt

* fix edit actions while only preview window is active

* add option to start telescope without previewer -> "disable_previewer_at_startup"

* remove hide / unhide prompt and resutls, improve hide / unhide preview

* fix tests - check if popup window should be created with borders - popup.create does not support setting borderhighlight and border=false

* allow toggle preview even if preview is set to false

* reuse recalculate_layout in hide / unhide preview

* add docs to toggle preview

* check if preview window is valid window

* remove unnecessary changes

* cleanup, remove unnecessary changes

* close all previewers, refactor toggle preview code
