Add DEFINE_HTMLELEMENT_TYPE_CASTS_WITH_FUNCTION() macro

Add DEFINE_HTMLELEMENT_TYPE_CASTS_WITH_FUNCTION() macro that generates better
type helpers for HTML Elements:
- Generates more isHTML*Element() helpers that are consistent with the ones
  in HTMLElementTypeHelpers.h so that there is no different in behavior /
  supported arguments.
- Supports more efficient isHTML*Element() helpers that take an HTMLElement
  in argument and thus don't need to check the namespace URI, only the local
  name.

This makes the manual isHTML*Element() helpers more consistent (and as
efficient) as the ones generated in HTMLElementTypeHelpers.h.

This way, when calling them, we don't have to worry if they accept a pointer or
only a reference, or if they are less efficient when we know the input element
is an HTMLElement.
