this is a part of a series to migrating from `operator<<(ostream&, ..)` based formatting to fmtlib based formatting. the goal here is to enable fmtlib to print `stream_reason` without the help of `operator<<`. please note, because we still cannot use the generic formatter for std::unordered_map provided by fmtlib, so in order to drop `operator<<` for `stream_reason`, and to print `unordered_map<stream_reason>`, `fmt::join()` is used as a temporary solution. we will audit all `fmt::join()` calls, after removing the homebrew formatter of `std::unordered_map`. the corresponding `operator<<()` are dropped dropped in this change, as all its callers are now using fmtlib for formatting now.
