[PATCH 4/4] org: Retain prefix arg when dispatching dynamic block commands

[Kyle Meyer]

* lisp/org.el (org-dynamic-block-insert-dblock): Add an interactive-p
argument that is non-nil for interactive calls and signals to call the
dynamic block function interactively.

org-clock-report takes a prefix argument.  When it had a regular
binding, this was easy to access.  As of 34b71a0ca (Add a dispatcher
command for inserting dynamic blocks, 2018-12-23), its only "binding"
is through the dynamic block dispatcher.  Make it possible to supply a
prefix argument in that context too.
