[ARM/AArch64][testsuite] Add explicit dependency on Neon Cumulative Saturation flag 

* gcc.target/aarch64/advsimd-intrinsics/arm-neon-ref.h
        (Set_Neon_Cumulative_Sat): Add parameter.
        (__set_neon_cumulative_sat): Support new parameter.
        * gcc.target/aarch64/advsimd-intrinsics/binary_sat_op.inc
        (TEST_BINARY_SAT_OP1): Call Set_Neon_Cumulative_Sat with new
        argument.
        * gcc.target/aarch64/advsimd-intrinsics/unary_sat_op.inc
        (TEST_UNARY_SAT_OP1): Call Set_Neon_Cumulative_Sat with new
        argument.
