The following patch uses project--list as a minibuffer history variable.
Now one can more easily switch between several related projects.

Independent from ongoing discussion about how to persist project--list
in bug#66993, this should be a useful improvement on its own.

This patch takes special care to avoid relying on savehist's persistent
mechanism, since savehist now knows about project--list as a minibuffer
history variable.

This patch does change the in-memory format of project--list, but not
the on-disk format, and project-known-project-roots still works, so this
patch should be backwards compatible.
