Remove visual effect of width cookies in tables

* lisp/org-colview.el (org-dblock-write:columnview): Remove :width
  parameter.

* lisp/org-table.el (org-narrow-column-arrow): Remove variable.
(org-table-cleanup-narrow-column-properties): Remove function.
(org-table-align): Ignore width cookies when aligning table.
(org-table-justify-field-maybe):
(org-table-finish-edit-field):
(org-table-follow-fields-with-editor):
(orgtbl-setup): Remove reference to `org-cwidth' property.

* lisp/org.el (org-mode):
(org-hide-wide-columns): Remove function.
(org-set-font-lock-defaults): Apply previous removal.
(org-shorten-string): Ignore `org-cwidth' property.

* testing/lisp/test-org-colview.el (test-org-colview/dblock): Remove
  a test.

Export back-ends may still use width cookie to alter table's output.
