Subject: [PATCH] Modularize theme selection for whichkey's telescope commands

Currently, each whichkey is configured slightly differently based on the
type of theme used for it.  This makes them all structured the same so
that it's easier to switch between dropdown or ivy.  The nice thing is
that one can then replace ivy{} with dropdown{} more easily.
