Kefu Chai e4463b11af treewide: replace boost::algorithm::join() with fmt::join()
Replace usages of `boost::algorithm::join()` with `fmt::join()` to improve
performance and reduce dependency on Boost. `fmt::join()` allows direct
formatting of ranges and tuples with custom separators without creating
intermediate strings.

When formatting comma-separated values into another string, fmt::join()
avoids the overhead of temporary string creation that
`boost::algorithm::join()` requires. This change also helps streamline
our dependencies by leveraging the existing fmt library instead of
Boost.Algorithm.

To avoid the ambiguity, some caller sites were updated to call
`seastar::format()` explicitly.
