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 `component_type` without the help of `operator<<`. the corresponding `operator<<()` are dropped dropped in this change, as all its callers are now using fmtlib for formatting now. also, please note, to enable fmtlib to format `std::set<component_type>` in `test/boost/sstable_3_x_test.cc` , we need to include `<fmt/ranges.h>` in that source file.
