I don't think its currently included in DW.   If you have javascript 
which requires the value and you don't wish to update the template, that 
implies you are supplying custom JS to DW via a plugin.  Following on 
from that you have a couple of alternatives ...
1.  Use an action plugin to add "<script type=\"text/javascript\"> var 
ID = $ID; </script>" or "<input id=\"dw_page_id\" type=\"hidden\" 
value=\"$ID\" />" string via one of the output events, 
TPL_CONTENT_DISPLAY, TPL_ACT_RENDER & TPL_METAHEADER_OUTPUT(*).
2.  Use an action plugin to add the data to a cookie.

I think TPL_METAHEADER_OUTPUT & <script> string is probably best.

(*) Its conceivable, though probably quite unlikely, that a template 
will not call tpl_metaheaders() which would prevent 
TPL_METAHEADER_OUTPUT event from firing.
