[PATCH gcc-15 0/1] libstdc++: avoid bf16 literal in format arg normalization

[Jakit Liang]

This patch updates std::basic_format_arg::_S_to_arg_type in <format>
on the gcc-15 branch to avoid a bfloat16 literal-based type check.

It replaces decltype(0.0bf16) with __gnu_cxx::__bfloat16_t while
preserving existing behavior by keeping normalization to float.

Tested on x86_64-linux-gnu.
