Kefu Chai 372a4d1b79 treewide: do not define FMT_DEPRECATED_OSTREAM
since we do not rely on FMT_DEPRECATED_OSTREAM to define the
fmt::formatter for us anymore, let's stop defining `FMT_DEPRECATED_OSTREAM`.

in this change,

* utils: drop the range formatters in to_string.hh and to_string.c, as
  we don't use them anymore. and the tests for them in
  test/boost/string_format_test.cc are removed accordingly.
* utils: use fmt to print chunk_vector and small_vector. as
  we are not able to print the elements using operator<< anymore
  after switching to {fmt} formatters.
* test/boost: specialize fmt::details::is_std_string_like<bytes>
  due to a bug in {fmt} v9, {fmt} fails to format a range whose
  element type is `basic_sstring<uint8_t>`, as it considers it
  as a string-like type, but `basic_sstring<uint8_t>`'s char type
  is signed char, not char. this issue does not exist in {fmt} v10,
  so, in this change, we add a workaround to explicitly specialize
  the type trait to assure that {fmt} format this type using its
  `fmt::formatter` specialization instead of trying to format it
  as a string. also, {fmt}'s generic ranges formatter calls the
  pair formatter's `set_brackets()` and `set_separator()` methods
  when printing the range, but operator<< based formatter does not
  provide these method, we have to include this change in the change
  switching to {fmt}, otherwise the change specializing
  `fmt::details::is_std_string_like<bytes>` won't compile.
* test/boost: in tests, we use `BOOST_REQUIRE_EQUAL()` and its friends
  for comparing values. but without the operator<< based formatters,
  Boost.Test would not be able to print them. after removing
  the homebrew formatters, we need to use the generic
  `boost_test_print_type()` helper to do this job. so we are
  including `test_utils.hh` in tests so that we can print
  the formattable types.
* treewide: add "#include "utils/to_string.hh" where
  `fmt::formatter<optional<>>` is used.
* configure.py: do not define FMT_DEPRECATED_OSTREAM
* cmake: do not define FMT_DEPRECATED_OSTREAM
