[ARM] PR target/71056: Don't use vectorized builtins when NEON is not available

        PR target/71056
        * config/arm/arm-builtins.c (arm_builtin_vectorized_function): Return
        NULL_TREE early if NEON is not available.  Remove now redundant check
        in ARM_CHECK_BUILTIN_MODE.

        * gcc.target/arm/pr71056.c: New test.
