*: recursive bump for fmtlib 12

Log message:
fmtlib: update to 12.0.0.
# 12.0.0 - 2025-09-17
- Optimized the default floating point formatting
  (https://github.com/fmtlib/fmt/issues/3675,
  https://github.com/fmtlib/fmt/issues/4516). In particular, formatting a
  `double` with format string compilation into a stack allocated buffer is
  more than 60% faster in version 12.0 compared to 11.2 according to
  [dtoa-benchmark](https://github.com/fmtlib/dtoa-benchmark):
  ```
  Function  Time (ns)  Speedup
  fmt11        34.471    1.00x
  fmt12        21.000    1.64x
  ```
  <img width="766" height="609" \ 
src="https://github.com/user-attachments/assets/d7d768ad-7543-468c-b0bb-449abf73b31b" \ 
/>
- Added `constexpr` support to `fmt::format`. For example:
  ```c++
  #include <fmt/compile.h>
  using namespace fmt::literals;
  std::string s = fmt::format(""_cf, 42);
  ```
  now works at compile time provided that `std::string` supports `constexpr`
  (https://github.com/fmtlib/fmt/issues/3403,
  https://github.com/fmtlib/fmt/pull/4456). Thanks @msvetkin.
- Added `FMT_STATIC_FORMAT` that allows formatting into a string of the exact
  required size at compile time.
  For example:
  ```c++
  #include <fmt/compile.h>
  constexpr auto s = FMT_STATIC_FORMAT("{}", 42);
  ```
  compiles to just
  ```s
  __ZL1s:
        .asciiz "42"
  ```
  It can be accessed as a C string with `s.c_str()` or as a string view with
  `s.str()`.
- Improved C++20 module support
- Switched to using estimated display width in precision. For example:
  ```c++
  fmt::print("|{:.4}|\n|1234|\n", "🐱🐱🐱");
  ```
  prints
  \ 
![](https://github.com/user-attachments/assets/6c4446b3-13eb-43b9-b74a-b4543540ad6a)
  because `🐱` has an estimated width of 2
- Fix interaction between debug presentation, precision, and width for strings
- Implemented allocator propagation on `basic_memory_buffer` move
- Fixed an ambiguity between `std::reference_wrapper<T>` and `format_as`
  formatters
- Removed the following deprecated APIs:
  - `has_formatter`: use `is_formattable` instead,
  - `basic_format_args::parse_context_type`,
    `basic_format_args::formatter_type` and similar aliases in context types,
  - wide stream overload of `fmt::printf`,
  - wide stream overloads of `fmt::print` that take text styles,
  - `is_*char` traits,
  - `fmt::localtime`.
- Deprecated wide overloads of `fmt::fprintf` and `fmt::sprintf`.
- Improved diagnostics for the incorrect usage of `fmt::ptr`
- Made handling of ANSI escape sequences more efficient
- Fixed a buffer overflow on all emphasis flags set
- Fixed an integer overflow for precision close to the max `int` value.
- Fixed compatibility with WASI (https://github.com/fmtlib/fmt/issues/4496,
- Fixed `back_insert_iterator` detection, preventing a fallback on slower path
  that handles arbitrary iterators
- Fixed handling of invalid glibc `FILE` buffers
- Added `wchar_t` support to the `std::byte` formatter
- Changed component prefix from `fmt-` to `fmt_` for compatibility with
  NSIS/CPack on Windows, e.g. `fmt-doc` changed to `fmt_doc`
- Added the `FMT_CUSTOM_ASSERT_FAIL` macro to simplify providing a custom
  `fmt::assert_fail` implementation
- Switched to `FMT_THROW` on reporting format errors so that it can be
  overriden by users when exceptions are disabled
- Improved master project detection and disabled install targets when using
  {fmt} as a subproject by default
- Made various code improvements
- Added Conan instructions to the docs
- Removed Bazel files to avoid issues with downstream packaging
- Added more entries for generated files to `.gitignore`
- Fixed various warnings and compilation issues

Log message:
fmtlib: update to 11.2.0.
# 11.2.0 - 2025-05-03
- Added the `s` specifier for `std::error_code`. It allows formatting an error
  message as a string. For example:
  ```c++
  #include <fmt/std.h>
  int main() {
    auto ec = std::make_error_code(std::errc::no_such_file_or_directory);
    fmt::print("{:s}\n", ec);
  }
  ```
  prints
  ```
  No such file or directory
  ```
  (The actual message is platform-specific.)
- Fixed formatting of `std::chrono::local_time` and `tm`
  For example ([godbolt](https://www.godbolt.org/z/8o4b1PPn5)):
  ```c++
  #include <fmt/chrono.h>
  int main() {
    std::chrono::zoned_time zt(
      std::chrono::current_zone(),
      std::chrono::system_clock::now());
    fmt::print("{}", zt.get_local_time());
  }
  ```
  is now formatted consistenly across platforms.
- Added diagnostics for cases when timezone information is not available.
  For example:
  ```c++
  fmt::print("{:Z}", std::chrono::local_seconds());
  ```
  now gives a compile-time error.
- Deprecated `fmt::localtime` in favor of `std::localtime`.
- Fixed compilation with GCC 15 and C++20 modules enabled
- Fixed handling of named arguments in format specs
- Added error reporting for duplicate named arguments
- Fixed formatting of `long` with `FMT_BUILTIN_TYPES=0`
- Optimized `text_style` using bit packing
- Added support for incomplete types
- Fixed a flush issue in `fmt::print` when using libstdc++
- Fixed `fmt::println` usage with `FMT_ENFORCE_COMPILE_STRING` and legacy
  compile-time checks
- Removed legacy header `fmt/core.h` from docs
- Worked around limitations of `__builtin_strlen` during constant evaluation
- Worked around a bug in MSVC v141
- Removed the `fmt_detail` namespace
- Removed specializations of `std::is_floating_point` in tests
- Fixed a CMake error when setting `CMAKE_MODULE_PATH` in the pedantic mode
- Updated the Bazel config
