Show Cider eval spinner in current evaluating file buffer instead of repl-buffer

[hierophantos]

Is your feature request related to a problem? Please describe.

I would like to control where the cider-spinner appears--specifically, in the file buffer where I'm eval'ing my code. Mentioned this in Slack: https://clojurians.slack.com/archives/C0617A8PQ/p1696125697359089. Others thought this would be a neat feature to have as well.

Describe the solution you'd like

Some sort of defcustom that I can set.

Describe alternatives you've considered

I have the above working for me, but it's probably too hacky to include as a PR. I modified two lines in cider-client.el and added one hook to my config to get the desired effect of having the spinner show in file buffer. The following are those changes; my code follows the commented out lines:

(defun cider-nrepl-request:eval (input callback &optional ns line column additional-params connection)
  "Send the request INPUT and register the CALLBACK as the response handler.
If NS is non-nil, include it in the request.  LINE and COLUMN, if non-nil,
define the position of INPUT in its buffer.  ADDITIONAL-PARAMS is a plist
to be appended to the request message.  CONNECTION is the connection
buffer, defaults to (cider-current-repl)."
  (let ((connection (or connection (cider-current-repl nil 'ensure)))
        (eval-buffer (current-buffer)))
    (run-hooks 'cider-before-eval-hook)
    (nrepl-request:eval input
                        (lambda (response)
                          (when cider-show-eval-spinner
                            ;; (cider-eval-spinner connection response)
                            (cider-eval-spinner eval-buffer response))
                          (when (and (buffer-live-p eval-buffer)
                                     (member "done" (nrepl-dict-get response "status")))
                            (with-current-buffer eval-buffer
                              (run-hooks 'cider-after-eval-done-hook)))
                          (funcall callback response))
                        connection
                        ns line column additional-params)
    ;; (cider-spinner-start connection)
    (cider-spinner-start eval-buffer)))

(add-hook 'cider-after-eval-done-hook 'spinner-stop)

Additional context

I needed to add the 'spinner-stop to the 'cider-after-eval-done-hook, because the cider-eval-spinner function wasn't seeming to receive the eval response, as far as I can tell.
