tracing: Use explicit array size instead of sentinel elements in symbol printing

tracing: Use explicit array size instead of sentinel elements in symbol printing

The sentinel value added by the wrapper macros __print_symbolic() et al
prevents the callers from adding their own trailing comma. This makes
constructing symbol list dynamically based on kconfig values tedious.

Drop the sentinel elements, so callers can either specify the trailing
comma or not, just like in regular array initializers.
