Update `org-get-property-block'

* lisp/org.el (org-at-property-p): Rewrite.  Don't use `org-element-at-point'.  It
is faster to retrieve the property drawer location instead.
(org-get-property-block): Update function and docstring.  Change
  signature.
(org-entry-properties, org-entry-put, org-buffer-property-keys): Apply
signature change.
