tracing: Allow tracer to add more than 32 options

Browse Source 
Since enum trace_iterator_flags is 32bit, the max number of the
option flags is limited to 32 and it is fully used now. To add
a new option, we need to expand it.

So replace the TRACE_ITER_##flag with TRACE_ITER(flag) macro which
is 64bit bitmask.
