Clean up various org-babel-*-maybe commands

* lisp/ob-core.el (org-babel-when-in-src-block): New macro.
  (org-babel-execute-src-block-maybe)
  (org-babel-expand-src-block-maybe)
  (org-babel-load-in-session-maybe, org-babel-pop-to-session-maybe):
  Use it.

org-babel-get-src-block-info is a potentially expensive operation, which
is why its ‘light’ argument exists.  But in any case, it is overkill to
query the whole info, if all that is needed is whether point is in a
block or not.  Factor the simplified common code out into a macro.
