Padding bits defeat intended HTMLEntityTableEntry size optimization

Reviewed by Chris Dumez.
Reordered the bitfields so they pack into two 32-bit units (21+5+1, then
14+16) instead of straddling unit boundaries, bringing the struct down from
12 bytes to the intended 8. Updated create-html-entity-table to emit the
members in the new order, and added a static_assert to lock in the size.
Thanks to Darin for initial idea on how to map these.
