libstdc++: Only use __builtin_sprintf if supported [PR 96083]

Clang doesn't support __builtin_sprintf, so use std::sprintf instead.

libstdc++-v3/ChangeLog:

PR libstdc++/96083
* include/ext/throw_allocator.h: Use __has_builtin to check for
__builtin_sprintf support, and use std::sprintf if necessary.

(cherry picked from commit 96d9670e88333d8896a5d2f2bb0403c1e2ad19ab)
