spacemacs-layouts: fix S/ivy-persp-switch-project

Fix #10177

counsel-projectile has updated custom actions mechanism[1] and
counsel-projectile-switch-project-actions is no more defined

Also,
 - moved counsel-projectile into spacemacs-layouts from ivy layer as
 perspective/layout based project switching depends on it instead of swiper
 - removed swiper from spacemacs-layouts
