Remove BalsaFrame::set_balsa_trailer() and BalsaFrame::trailer().

This CL removes BalsaFrame::set_balsa_trailer(), which now has no remaining
usages, in favor of BalsaFrame::EnableTrailers(). This CL also removes
BalsaFrame::trailer(), which now has no remaining usages. This CL will enable
the removal of BalsaVisitorInterface::ProcessTrailers().

Thanks to ++bnc@ for migrating BalsaParser in Envoy to the EnableTrailers() API
(e.g., [1, 2]), which was also helpful/important for enabling the deprecation
of set_balsa_trailer().
