Moving the html5 atoms out into their own initialization phase makes the
initialization of atoms more explicit and avoids problems with trying to
move modules around so their atoms get initialized in the correct place.
As an aesthetic bonus, this change produces pleasing symmetry in
nsHtml5Module::{Initialize,Release}Statics.
