libstdc++: Disable broken std::format for floating-point types [PR108221]
If we don't have std::to_chars for floating-point types (either because
float and double are not IEEE format, or size_t is 16-bit) then we can't
use them with std::format. This causes a bootstrap failure since
std/c++20/tzdb.cc was added to the library, because <chrono> now
includes <format>.
This change just disables formatting support for those types. This is
not a proper fix, but solves the bootstrap failure for now.

* include/std/format (basic_format_arg) [!__cpp_lib_to_chars]:
Disable visiting floating-point types.
