Do not use visual `current-indentation' when we need real values

* lisp/org-macs.el (org-current-text-indentation): New macro
calculating the real text indentation disregarding buffer visibility.
(org-do-remove-indentation):
* lisp/org-src.el (org-src--edit-element):
* lisp/org.el (org-indent-line):
(org-indent-region):
(org-toggle-fixed-width):
(org-comment-or-uncomment-region):
* lisp/ox.el (org-export-expand-include-keyword): Use
`org-current-text-indentation' instead of `current-indentation' and
`org-current-text-column' instead of `current-column' when we need
real text values but not visible values.
