Remove CXFA_TraverseStrategy_ContentLayoutItem.

It makes illegal casts and requires its callers to double-check the
type validity of results before use. Instead, use the parent
class iterator and perform checked casts.

No functional difference, since it looks like the requisite checks
were being made in all places.

Make one "using" visible to other files to save some verbosity.
