Respect global-eldoc-mode in minibuffers (Bug#36886)

* lisp/emacs-lisp/easy-mmode.el (define-globalized-minor-mode): Accept
a BODY parameter.
* doc/lispref/modes.texi (Defining Minor Modes): Document new
parameter.
* etc/NEWS: Announce it.

* lisp/simple.el (read--expression): Move eldoc-mode setup to...
* lisp/emacs-lisp/eldoc.el (eldoc--eval-expression-setup): ... here,
new function.
(global-eldoc-mode): Add or remove it to
eval-expression-minibuffer-setup-hook when enabling or disabling
global-eldoc-mode.  This enables eldoc in the minibuffer (solving
Bug#27202), only when global-eldoc-mode is enabled.

 This defines a global toggle named @var{global-mode} whose meaning is
 to enable or disable the buffer-local minor mode @var{mode} in all

+mode in a buffer, it uses the function @var{turn-on}; to turn off the
+minor mode, it calls @var{mode} with @minus{}1 as argument.
 
 Globally enabling the mode also affects buffers subsequently created
 by visiting files, and buffers that use a major mode other than
