Entity-encode E<0xNNNN> and E<0NNN> correctly

Fixes bug #68964 reported by samv, where pod2html encoded E<0x2070> to
&0x2070 and not &#x2070. perlpodspec says E<0x2070> should work, but the
code in Pod::Html accepted only E<x2070>. The new code accepts both, and
processes octal entities correctly as well.
