Rewrite switch-{buffer,window} hooks

+ Add doom-switch-frame-hook
+ Replace doom-{enter,exit}-{buffer,window}-hook with
  doom-switch-{buffer,window}-hook
+ New switch-buffer hooks run on buffer-list-update-hook rather than
  in select-window advice.
+ Blank our buffer-list-update-hook in some places to reduce how many
  times it gets triggered.
