  Fix VS2013 build of QUIC radix tests

Visual Studio 2013 does not provide the C99 __func__ predefined identifier =
in C mode. Use OPENSSL_FUNC, which maps to the compiler-supported equivalen=
t.

This is the only source change required to compile current master with VS20=
13 Update 5 (cl 18.00.40629), on both x86 and x64.

  Fix C99 printf length modifiers with VS2013 CRT

The Visual Studio 2013 CRT does not support the C99 z, t and j length modif=
iers. Passing such formats to _vsnprintf_s invokes the invalid-parameter pa=
th and normally terminates the process.

For _MSC_VER < 1900, translate z and t to the pointer-sized I modifier and =
j to I64 before calling the CRT. Allocate a translated format only when nee=
ded, leaving newer MSVC versions and unaffected formats unchanged. Delegate=
 BIO_snprintf to BIO_vsnprintf so all BIO formatting entry points use the s=
ame compatibility path.

Add focused coverage for BIO_snprintf, BIO_vsnprintf and BIO_printf, includ=
ing the large-output allocation path and truncation behavior.

Fixes #31645
