x86/paging: Enforce PG_external == PG_translate == PG_refcounts

Setting PG_refcounts but not PG_translate is not useful.

While adjusting this, make a few other improvements.

 * Have paging_enable() unilaterally reject any unknown modes.
 * Drop the or'ing of PG_{HAP,SH}_enable.  The underlying functions already do
   this.
