org-latex-preview: Ignored cmds list for auto mode

* lisp/org-latex-preview.el (org-latex-preview-auto-blacklist): Add a
blacklist for commands that should not cause LaTeX preview overlays to
be "opened", i.e. for preview images to be hidden and text revealed when
using `org-latex-preview-auto-mode'.  A common use case would be cursor
navigation commands like `next-line' or `scroll-up-command' that are
often intended to move the view of the buffer, where opening preview
overlays can be distracting.
