gsignal: Mention handler ID type in signal connection macro docs

gtk-doc doesn’t make the return type clear, because these are macros
rather than inline functions, so people often have to guess at the
return type (or look it up from g_signal_connect_closure(), but that’s
hard work).

Make it clear that the return type for handler IDs is gulong. While
there, fix the capitalisation of ‘id’ to ‘ID’ in a few places.
