This PR proposes using the existing
rand_hwrng.goimplementation ofhardwareRand()for RP2040/RP2350.On these targets,
hardwareRand()callsmachine.GetRNG()on every invocation, so themath/randglobal RNG always obtains randomness and does not fall back tofastrand64().This makes
hardwareRand()behave as its name suggests, at the cost of lower performance.
