Test on H5 HW wire WOLFBOOT_TZ_TEST_NO_BKPT make-flag through CFLAGS

  The auto-test block in app_stm32h5.c gates its bkpt #0x7f / #0x7e on
  WOLFBOOT_TZ_TEST_NO_BKPT, but the make-flag was never propagated to
  CFLAGS. Building with make WOLFBOOT_TZ_TEST_NO_BKPT=1 now actually
  swaps the BKPTs for printf(WOLFHSM_TZ_TEST_{PASS,FAIL}) + while(1)
  loops, which is the canonical hardware-test path (per D25) since
  real silicon HardFaults on bkpt without a debugger attached.

  Verified on NUCLEO-H563ZI hardware:
    wolfHSM CommInit ok (client=1 server=56)
    wolfHSM RNG ok: <16 random bytes>
    wolfHSM NSC tests passed
    WOLFHSM_TZ_TEST_PASS
