configure, msvcrt: Check for the finite() function just like finitef().

If missing, fall back on the C99 isfinite() macro, just like the existing finitef() fallback. The finite() function is deprecated in macOS 10.9 and is removed (from the SDK) since macOS 11.0. Signed-off-by: Martin Storsjo <martin@martin.st> Signed-off-by: Alexandre Julliard <julliard@winehq.org>
